World Building and Terrain Editor Manual

The tutorials in this World Building and Terrain Editor user manual cover how to create  a new world, scene, and terrain, followed by sculpting, painting, importing, building/optimizing, and extending (for large multi-tile worlds), and procedurally generating and painting the terrain.  
This manual also covers filling in the world with detail including realistic Land Cover for vegetation (plants, trees, grass) and natural features or objects (such as rocks) using Land Cover brushes and procedural Land Cover generation, as well as using the Object Brush placement mode for entities in Scene Editor, and placing decal textures onto the terrain for additional detail and texture blending. 

All of this is done using the Visual3D All-in-One Toolset's built-in Terrain Editor, Scene Editor, and other powerful integrated tools for real-time world building.


Terrain Creation Tutorial

Part 1. Creating a New Scene with Terrain

Step 1. Startup the Toolset to Edit (or Create) a World Project

  1. Start Visual3D from the desktop shortcut.  
  2. Select "Tech Demos" World.   
  3. Check the "Launch Architect" checkbox to startup the toolset (so you can edit it, instead of starting in run/play mode).  
  4. Then, press the "Open World" button. This will launch that world project in the toolset.




Step 1B. Or, you can create a new world project

Alternatively, instead of selecting an existing world project like Tech Demos to edit, you can create a new world by selecting the "Create New World" option and enter a unique world project name there, then press the button for Create World.

However, for this tutorial, we show editing the existing Tech Demos world.

Step 2. Create a New Scene

From the Main Menu, select "Create New Scene" from one of two places: (a) the top menu green button, or (b) right-click on the World Explorer top node labeled "Tech Demos" and select from menu.

          OR     

Click the New Scene button in World Explorer toolbar  OR   Go to File (Visual3D icon) menu and select > New Scene:

 

 

Name your scene and select the terrain and sky presets to use for it:




 Step 3: Create a Terrain for the Scene

 


 

Step 4 (Optional): Import Heightmap (or DTED or GIS DEM Data) and/or Aerial Imagery 


This video shows terrain creation from heightmap and optional aerial imagery. 
Also, screenshots summarizing the main steps are found below, as well as in our Importing Terrains from DTED and GIS DEM Data tutorial screenshots (though that is covered in more detail below and in the procedural painting section of this user manual).
 

Select Heightmap (or DTED or GIS DEM Data) to Import:




 

Select Imagery to Import:


Multiple Tiles with DEM (GIS Data/Heightmap) and optional Imagery (Imported Texture)


You can also define multiple terrain tiles, each with a different heightmap or DEM/GIS data and different imagery, as described in the Multiple Tile Creation section, which shows how you can add new terrain tiles or import a different heightmap/DEM or imagery for an existing tile.
If you had imported an aerial imagery texture, you can change the terrain painting (Runtime Blending) mode in the Terrain Tools > Paint panel, to Imagerly Only or Painting Only (which uses auto-generated imagery based on painting done in toolset, replacing any imported imagery) or a blended combination of the tool, as is described further under  the Painting Terrain and Procedural Painting sections.


Part 2. Sculpting the Terrain


This video shows different terrain relief modifiers in action.


Part 3. Painting the Terrain


The above video shows terrain painting and paintbrushes tuning, and our Sculpting & Painting screenshot-based written tutorial covers this further.

Terrain Texturing with Imported Imagery, Tiled Texture Painting (Splatting and Auto Generated Imagery LOD) or a Blended Combination

You can change the Terrain Texturing mode, using the Runtime Blending drop down in the Paint tab of the Terrain Tools panel (or the Terrain Painting Mode property in Object Editor when the terrain is selected) to either use only the imagery texture for terrain coloration (Imagery Only mode, which may be the default when imagery was imported), or to Painting Only (ignoring or automatically replacing any imported imagery texture, and just using the tiled splatting textures applied using paint brushes and procedural painting in Terrain Editor, which provides a higher resolution appearance for terrain and is the suggest default for mode terrains), or which uses a blended combination of there two (where you can adjust the blending factor under Painting in Object Editor when the terrain is selected, which also affects blending of Near and Far Painting tiled texture layers with the auto-generated imagery in Painting Only mode).

Part 4. Procedural Painting of the Terrain


With Imported Aerial Imagery Only:


After Procedural Generation of Painting (Splatting) Blended with Imported Aerial Imagery:

 

Part 5. Optimizing Terrain: Building Geoclipmap LODs or Optimized Mesh

This tutorial shows how to Build/Optimize your terrain once you have finished editing it, to optimize its performance for it.  It is suggested, though not neccissary, and you can always build a terrain later before publishing, and can edit and optionally rebuild after that, as well.

The first part of the tutorial covers building in the default build mode, which is optimized for larger terrains/worlds, by enabling terrain paging/streaming and LODs.
The second part of the video shows using the alternative build mode, which instead generates a single optimized triangle mesh for your editable terrain, with, though it doesn't currently support LODs, may provide better performance for smaller terrains as well as provides variable geometry detail based on the complexity of the terrain (so that cliffs have more polygons than flat areas).  
You may want to try both modes, adjusting the settings shown in the video for balancing quality vs. performance (and faster build time), before deciding which is best for your terrain.



This video shows different terrain rendering modes.

 

 

  1. Visual3D uses one of the most advanced terrain systems on the market. Did you know that?

  2. Visual3D is capable of rendering terrains of unlimited sizes (only limited by disk size, RAM size, and detail to performance requirements).

  3. But to see your terrain in this mode, there is a slight cost -- you must Build it! Typically, this takes a few minutes, for a single tile.

  4. As we continue to optimize it further, you will see increasingly large examples of huge multi-tile terrains, with some support for setting them up inside Architect tool set directly.

  5. Anyhow -- on to business now -- to see your terrain in it's full glory (most optimal format) -- you must click "Build/Apply" at top of screen, and then wait it out.

  6. Go get some coffee, or relieve bodily pressures, or call your mother or someone dear to you. Don't waste these precious few moments by waiting on Visual3D.

  7. Visual3D is here to increase your quality of life and your happiness. It is not here to waste your time, or make you wait.

  8. So please, do not just sit there and stare at the screen -- it makes Visual3D feel very self-conscious and bad. Go find something to do for a few minutes, please!

  9. Ok -- now you are prepped to do the build. Click "Build/Apply" and go do your thing!

  10. If you haven't bought your own license to Visual3D yet, you should have just enough time to complete the transaction before the build completes. And when you do this, pat yourself on the back and say something nice to yourself. You have just done a very great thing, as your precious money will be used for food, shelter and internet service for the very dear developers who brought you this wonderful product. Just keep in mind all of the "Great Skills" you are learning, and appreciate the great successes Visual3D will bring to your doorstep. Now isn't that worth it?

  11. OK -- now it's about time for the build to be done, so that you can see your terrain in all of its glory.

 


Part 6. Fine Tuning for Optimized Mesh Terrains

(Note: This only applies to terrains which have been Build/Optimized in the new "Optimized Mesh" mode, not the default mode of "Geoclipmap" which builds LODs for paging terrain and is currently better suited for larger worlds).


This video describes optimized terrain mesh tuning close up.


 

Part 7.  Creating Massive Worlds: Adding Multiple Tiles or Heightmap Layers

1. Select TerranSettings in World Explorer, or terrain settings will be selected automatically when you select the Terrain tab and the Sculpting tab in the Terrain Tools window.


 

2. Add a new tile in the Object Editor.




3. Adjust the new tile (by default Tile1).
Enter World Cell Coordinate X = 1 and Y = 0. This means that all your terrain (with many tiles) is spaced by cells, and 0, 1 means that tile has 0 offset in cells by X axis and 1 offset in cells by Y axis. For instance, if you want to have a terrain with 2x2=4 tiles, your tile coordinates in cells will be: [0][0], [1][0], [0][1], [1][1].




4. Edit (sculpt or paint) the new tile in the Terrain Editor.

a. Make double click in the World Explorer.

b. Use a context menu in the Object Editor.


 

 

Part 8. Using and Adjusting Brushes for Painting and Sculpting

Terrain Editor User Controls Reference

The above link is to shortened version of the older Terrain Terrain Editor Introduction Tutorial, which includes voice over narration, showing and describing the user controls for moving the camera around, adjusting painting/sculpting brush parameters, changing brush/tool modes, and fixing mistakes with "undo".
 

We will give you some quick pointers here.

  1. Use your Middle Mouse Button + Drag a lot --- this allows you to grab any piece of the terrain an pivot around it to get your perfect view angle!

  2. Then use the Mouse Wheel to Zoom in and out!

  3. If you wish to "Free Fly" around, use WSAD keys, and if you want to "levitate up/down", then press SHIFT key while using the Wheel Up or Down.

  4. Right-Click + Drag to turn the camera.

  5. Left-click to use the current brush -- so be careful! It's loaded!

  6. If you mess up, don't hesitate to use Ctrl+Z to "undo". It really works!

  7. To adjust the 3 main Brush settings, press the "Ctrl" key along with one of the 3 mouse buttons plus drag, to adjust these settings. Each Mouse button is bound to a separate setting as follows:

    1. Ctrl + Left mouse button + Drag : Adjusts brush Size. Drag right to increase, and Left to decrease.
    2. Ctrl + Middle mouse button + Drag: Adjusts brush Hardness. Drag right to Harden, and Left to Soften.
    3. Ctrl + Right mouse button + Drag: Adjusts the brush Speed/Strength (affects how fast the effect is applied)
  8. Note that for all 3 adjustments, there is a separate visualizer shown on the brush to help you do everything local without the inconvenience of having to leave the render window to adjust these settings. This is very convenient!

  9. When applying the brush (using Left-button press and hold), the SHIFT key can in many cases be used to "Reverse the direction" and the Alt key can "slow down the effect".

 

Part 9.  Using the Decal Editor for Adding Detail and Blended Textures Addons onto Terrain

Checkout our new Decal Editor Tutorial for how to use Decal Editing to drag-drop Textures onto the terrain for everything from added terrain detail (such as for leaves or gravel/small rocks, patches of grass, cracks, etc.) to explosion blast marks, puddles, and other effects.

Visual3D Decal Editor for Drag-dropping Textures onto Terrain  Visual3D Decal Editor for Grass, Moss, Oil Spills, and Other Terrain Painting Addon Effects


Part 10. Brush-based Object Placement

Object Brush Placement mode is enabled by selecting the different Brush toolbar buttons in the Scene Editor toolbar in the Design tab and then selecting an entity, depending on the brush mode and left right or middle mouse button used (and whether Ctrl, Alt or Shift is held down) will either place an object periodically (for example, every half second, as configurable under World Settings) or every time the mouse button is clicked, without needing to drag-drop the same entity prefab or model from Asset Explorer onto the Scene Editor viewport each time.
This scene editor tool mode for object/entity placement is used for quickly adding many copies of an entity to the scene, such as for Vegetation, Rocks, or even buildings and characters.  

See the Object Brush Placement Mode section of the Scene Design world manual for more details.

However, it is suggested instead in many cases that Land Cover painting be used instead for vegetation, rocks, etc., at least when fine tuning with exact placement of each individual entity instance is not needed, because Land Cover supports more advanced LOD logic with procedural placement based on a density map (similar to terrain painting) together and supports increasing and decreasing viewing distance and density, as well as automatic impostering (interpolated multi viewing angle sprite LODs) and other more advanced LOD techniques (including configurable distance at which collision will occur from the camera) an can therefore be more efficient and compact than brush based placement.   

 

 Terrain Sculpting and Painting Walkthrough: Creating a Mountain Pass

Note: This walkthrough tutorial shows and describes screenshots which show an older version of the Terrain Editor user interface and its painting and sculpting tools, so we suggest getting started by watching the video tutorials found above first, as they cover painting and sculpting as well, and then reading through this tutorial if you want more detailed tips and examples of how to effectively make use of these tools.

In this tutorial, we will walk you through the steps of creating a new scene based on Lost Isle, and then inside this new scene, you will create a mountain pass that meanders up the mountain side to near the peak, and then down the back side. You will be able to drive or walk this new path through the mountain, and enjoy the short-cut of not having to go around the mountain. Who doesn't like a nice scenic short-cut?






Step 1. Let's Practice by making a simple Mound.

  1. Using your newly acquired Camera manipulation skills, maneuver your camera down to the mountain side pictured below. The easiest way to do this is to Middle-Mouse Click the ground you want to move towards, and then roll the Mouse Wheel Up (or forward) until you zoom to that location. Very fast and convenient.

  2. Make sure the "Sculpt" tab is selected in the Terrain Editor panel at the top left side of your tool set window. Then select the "Raise" sub-tab beneath it (both should already be selected normally).

  3. To get some easier practice, let's start out with a sample mound. Pick out some flat territory near you, and start there.

  4. First let's slow down the brush to about "10". To do this, with mouse in the render window, press CTRL + RightMouseButton + drag to the Left, until the Strength reads about "10".

  5. Now place your circular brush where you want to create a mound, and press the Left Mouse button in short-spurts, and drag the mouse a bit as the ground rises.



Step 2. Sharpen the Edges - Make it more Dramatic


  1. Now that we have some odd looking mounds in our ground, let's do something more interesting with them.

  2. Switch your brush type from "Raise" to "Smooth".

  3. Note, that if you press SHIFT while applying this brush - it behaves in the opposite fashion to Smooth -- which we call "Sharpen".

  4. Shift+Smooth = SHARPEN.

  5. This is a great way to amplify the ridges and detail that are already there, to create a more dramatic mound.

  6. Press SHIFT + LeftClick and slide your brush over top the mound until you get the effect you like.

  7. If you don't like the effect, just press Ctrl + Z to Undo until it's back to a good state again. (our undo buffer right now is small, so don't count on more than 10 undo's at once)

  8. Also, you might want to play around with the sub-settings for Smooth Brush, called "Filter Radius" (defaults to 3 meters) and "Anti-Spikes" (defaults to 1.0).

    1. Filter Radius affects the size of the filter, which is essentially the size of circle around which each point is being averaged against.
    2. "Anti-spikes" feature is meant to help you eliminate a common artifact of height maps known as "stair stepping" or "saw tooth ridges". If you see any "saw tooth" ridges, you'll know it instantly. And you can get rid of these by turning up "Anti-spikes" to 3.0 and turning down the "Filter Radius" to about 1.5. Of course many settings will work, and so it's just a matter of you getting the feel of it.
    3. Note, that if the Smooth brush is "going to slow" in areas where you are not dealing with spikes -- you can usually speed it up more, by reducing the "Anti-Spikes" to 0.0.


Step 3. Now let's paint it to match the rest of the scene.


  1. As you might notice, this new mounds now look just a little bit "mutant". They don't quite match the rest of the scene.

  2. Enter "Procedural Brush". The key to making it match is to use the same Procedural Brush as has been used to the rest of the scene (except for the dirt road).

  3. Select the "Paint" tab in the Terrain Editor. Then double-click the "<Procedural Brush>" shown in the "Texture Layers" below.

  4. From the selection dialog, select "Lost Isle 3 - Procedural Paint 1 -.." option by double-clicking it.

  5. Now this procedural brush will be active! Press the Left Mouse Button and drag the brush overtop your Mound, until it looks "just right".

  6. You should see more Rock being colored onto this mound, to match the style of the other mountains and hills in this scene.

  7. Now your mound looks more like all the others! Sweet, you did it!

  8. How does yours look? Like a professional, eh?

  9. Feel free to experiment with the various brush types on this mound. Go ahead and mess it up badly if you like.

  10. It's important to experiment freely until you get comfortable with the tools.

  11. Feel free to start over from scratch with a new scene as many times as you like. It's easy. It's fun. It's worth it! ;)

  12. After you work this for a while -- you will have acquired yet another "great skill" to attract those of the opposite gender (... or the same in some cases).




Step 4. Now Let's make a Path!


  1. Position your camera now back over by the mountain shown in the diagram below. We're going to make a Mountain Pass that you walk or drive on!

  2. One of my favorite brushes to use for this is the "Flatten" brush turned down low, so that it behaves more like a "smudge tool".

  3. You might have to watch the video tutorial (not published at the time of this writing) to see the best techniques for making a sloped path, as we are going to do now.

  4. The secret is short and quick strokes with the Flatten brush turned down fairly low (usually 20 is a good place to start). As you get better with it, you can turn up the strength and achieve the same results even faster.

  5. If you work really hard, and stay focused, you might become just as masterful as me at this! Won't you be proud then?

  6. Again, I must remind you that mastering the Flatten brush, is considered yet another "great skill" useful increasing your romantic appeal. So take it very seriously, and great things will happen to you.

  7. Check out the path I made in the diagram below using only the Flatten brush. Amazing, eh?




Step 5. Now Finish the Path!


  1. Feel free to experiment with the various brushes to produce the desired effect.

  2. Consider using the "SHARPEN" effect (SHIFT+Smooth == SHARPEN) along the edges of your path to raise the edges and create a nicer looking result, with more drama.

  3. Carefully, with short-strokes of a low powered Flatten brush, carve your path up the mountain side, and meander as needed to create a more gradual pleasant slope.

  4. Don't let existing peaks get in your way -- that's what "Flattening" is all about!

  5. Visual3D makes you semi-god-like. You can flatten mountains with the click and stroke of your mouse-wielding wrist! So watch out that you don't hurt anyone too badly.

  6. Please feel free to recreate your scene from scratch and try again many times, until you get it right.

  7. For smaller scale mess-ups, just use Ctrl+Z to bring your terrain back to a "Good state", but remember the Undo Buffer only holds up to 10 actions. (It will be increased in the future.)

  8. See the top-view below, how I masterfully carved a complete new Mountain Pass into my own new version of the Lost Isle terrain. Amazing!

  9. Did you wet your pants yet? Not even a little? Come on, fess up.




Step 6. What good is an Unpainted Path?


  1. Are you ready to Paint? Great. This is yet another "Great Skill" that will help you be successful and popular in life.

  2. Let's use our trusty Procedural brush, which may already be set to the correct "Lost Isle" default. If it's not, then select it now, as shown in step #5C above.

  3. You should be getting better at this by now. Go ahead and paint the path with this brush. Wow, looks nice, eh?




Step 7. Use the "Dirt Road" brush to Differentiate it.


  1. Since the Path should differentiate itself from the rest of the mountain, I suggest you use the "Dirt Road Brush" now, and repaint all or parts of the path.

  2. Do you like the new effect? I hope not... because who wants to paint with someone's else's brush??? Especially when you can customize your own. (shown in #7C below)



Step 8. Modify the "Dirt Road" brush to be more to your liking.


  1. Your current Active Brush settings can be found in the "Object Editor" on the right side of tool set.

  2. With "Terrain Settings" selected (which should be by default), open up the "Procedural Painting" section by clicking the "+" plus sign.

  3. Oh, oh!! This looks scary!!! This is where you see the less-elegant parts of Beta 6! We have plans to make this part more elegant for future releases.

  4. But this will do for now. Don't be scared, "you can do it!" Just repeat this to yourself "I think I can, I think I can... " then "I know I can, I know I can..." And just like the little train, you will succeed!

  5. Now just to warn you -- the skill you are about to learn here is a bit mathematical in nature. You will be tweaking percentages "%", Slope Ranges (degrees), and edge bias filters! (what the heck do you mean by edge???)

  6. Here is how it works....

    1. Each Procedural Paint Brush consists of a set of "Altitude Layers".
    2. Each "Altitude Layer" consists of a set of "Layers" that are applied only to the Altitude range specified. This allows you to differentiate the Painting logic that is applied for each altitude! Nice... right?
    3. Each "Layer" allows you to specify a "Strength" and also an optional "Slope" and "Edge" filter. (see definition of these below)
    4. You can apply as many layers as you want! The possibilities are limitless! (who we do like some limits, so this isn't that exciting, now is it?)
    5. Ok -- are you still scared? A little? Well, keep pushing forward.
    6. Here are the definitions to learn here: (there will be a closed-book test, so be ready)
      1. "Slope" filter allows you to specify at which slope ranges the Paint will be applied. Range is from 0 to 90 degrees.
      2. "Edge" filter allows you to specify the "Edge bias" where Paint will be applied. So what is an Edge bias? In short, it is calculated by comparing the relative height of each terrain point to the points around it. For points that are "higher than average", they will have a positive edge value, while points that are "below the local average" will have a negative edge value. This allows you to differentiate between "Peaks" and "Valleys" or "Ridges " and "Trenches". This is very useful to be able to make your Paint "follow the contours". Notice how this technique is used in Lost Isle to make the "ridges are rock" while the "trenches are light colored grass". Looks nice, eh? Come on, you know you like it.
      3. "Max/Min Ramp" values is the range across where the Paint is faded in or out. Higher Ramp values mean "more gradual fading" while very low Ramp Rates mean "instant transition". Typically values range between 0 to 2. Note, that the Fade In/out start or end at the Filter boundary. (the feathering is "inward" not "outward" -- I hope that makes sense...?)
    7. NOTE: You can read the "Altitude", "Slope" and "Edge" value for any point in the scene by putting the mouse cursor over it and reading it from the bottom of the render window! Convenient, yes?
  7. Are you worn out yet? Does your brain need some ice? Or maybe more likely, you might be asleep or in a trance by now.

  8. Wake-up! It's time to fiddle with some values! If none of this makes sense, then just go crazy with modifying values randomly -- and after each set of changes -- try painting in the scene, and see the result!

  9. Is it getting more fun yet? Keep on doing this - and eventually you'll create an effect that you like.

  10. Ok -- backing up now -- you can do just something simple now with us.

  11. Reselect the "Dirt Road Brush", and then open up "Altitude Layer 0", and then open up "Layers 1" (the Grass Layer). We want to make this dirt road "more grassy". (who likes all that dirt anyways?)

  12. Change the Strength of this layer up to 500%, which will make it overpower the Dirt in some places (anywhere the slope is > 1 degree).

  13. Now paint with it, and see much of your dirt turn to Grass.

  14. Play with more settings until you achieve the right result, to match your tastes.




Land Cover Tutorial: Adding Vegetation (Trees, Plants, Grass), Rocks, and Objects via Brushes and Procedural Generation

Additional Documenation Related to Land Cover: 
  1. Trees, Vegetation, and Land Cover - Models and Wind Animation


Step 1. Adding Land Cover

  1. Now it's time to add LandCover to our Mountain Pass Scene.

  2. Click on the "Terrain" tab to top of Scene window, and then click the "LandCover" tab over in the "Terrain Tools" panel. See all the pretty colors?

  3. If you remember when we selected "Create New Scene", we selected to "Add LandCover" which inherited the LandCover from Lost Isle. So we have the same Placement Map.




Step 2. Erasing Land Cover (Clearing a Path)


  1. Notice from the diagram above, how we have LandCover on our new Path. This is not good. We want a clear path.

  2. So before we go further, let's erase this Landcover. Click the "<Erase>" brush from the Terrain Editor panel.

  3. Then LeftClick + Drag to Erase the LandCover from the near ramp we built.



Step 3. Now Let's See our LandCover in Run Mode.


  1. Note that for Beta 6, LandCover objects will not spawn while in Terrain Editing mode. They only spawn in Run Mode. This will be fixed for a future release, for your convenience.

  2. Click on the "Run" tab at top of Scene Window.

  3. A warning should show (as seen below) to indicate that you have not yet defined LandCover Objects to be placed. So you have a Placement Map -- but no Objects defined yet.

  4. Notice in the Object Editor, that the "Object Definitions" list is currently empty.




Step 4. Select a Predefined Object Collection -- "Birch Tree Sample" -- Yuck!


  1. To select a predefined set of Objects, click the "..." next to "Object Definitions" in the Object Editor, as shown below.

  2. Then select the "Birch Tree LandCover Sample 1" collection from the dialog, as shown.

  3. When you are done, the result will instantly show up in the scene! Nice... err, maybe not -- looks kind yucky to me.

  4. Not that I have anything against Birch Trees, but according to my taste -- they just don't seem to fit here in our version of Lost Isle with this paint palette.

  5. Just looking at it makes me want to heave. Please change it, please change it....!! Please. Don't tell me that you like it -- I know you are lying.


Step 5. Make a better selection. Let's pick the Lost Isle collection.


  1. More love has clearly been poured into the Lost Isle Collection. Let's choose it instead.

  2. For fun, let's do this in another way. Try this instead.

  3. Find "Lost Isle Dying - Objects" collection in the Asset Explorer. It's found under "Environments->Landcover->LC Object Collections".

  4. Or you can just type "Dying" into the Filter at top, and it will show you the few selections that match. Or you can use Group Filter to only show you the LandCover types.

  5. Once you find it, Drag&Drop it from the Asset Explorer onto the Scene Window, while in Run Mode.

  6. Instantly, the LandCover collection will change over to the new collection. Elegance, right? You know it.

  7. Ahh, now that looks nice. Now don't be shy -- move your camera over near the trees and see the shadows, and all their glory.


Step 6. "Let's take a Ride in an Automobile, Let's take a Drive in a car!"


  1. Now it's time to test out our craftsmanship by driving over top it with a dune buggy.

  2. Move your camera to the base of your ramp.

  3. In "Asset Explorer" type the word "Buggy" into the filter box, and you will see the "Buggy" entity showing below.

  4. Now Drag/Drop the "Buggy" entity near base of your new ramp.

  5. Are you ready to take a short-cut through the mountains?




Step 7. Drive/Walk/Run Across Your Terrain


  1. Double-click your buggy to take control of it

  2. Use the WASD keys to steer and accelerate it. Use <Space> for "braking" and "B" for the horn ("[B]eep!").

  3. Drive your buggy through the mountains up one side, and down the other.

  4. How was it? Do you need to make changes to your path? If so -- have at it! We must make this a fun path to drive.




Step 8. Oops, we forgot to clear the Trees on the other side!!


  1. Unless you took care of this without me telling you (and if so, "good for you!"), you will now notice that there might be trees populating the down ramp on the other side of the mountain.

  2. Now take a breath, and don't freak out. We can deal with this.

  3. Ah yes, here's how. Switch into Terrain Edit Mode, and Select the "LandCover" tab from Terrain Tools (just as before).

  4. Now you will see the coloration on your ramp. Use the "<Erase>" brush as you had before, to clear the plants away from your path.

  5. Now click "Run" tab, and that's all there is to it!

  6. Save your scene, so that later you can show off the results of your "Great Skills" and watch your romance life flourish.

Step 9. Have some fun!


Don't forget to play around with your new creation. Drop in some buggies, and away you go. To bring a buggy to life, just double-click it, and then press <Escape>. This activates its own primitive AI, so that it will begin to drive solo. Then you can drop in a buggy for yourself, and join the fun.

That's it. I hope you enjoyed the tutorial. Now that you have new "Great Skills", put them to work for you, and tell us about your great success on our forums!

We would love to see screenshots of your original creations, posted to our forums -- whether grand or ugly! All submissions are welcomed.
