- 3DS Maxscript that exports 3DS Max mesh to Unity terrain
- Whats nice, you a have full control of the terrain mesh in 3DS Max
(edit as much as you like, stack modifiers, edit few/single vertices etc..) & then easy export to Unity)
- This plugin/script doesnt generate any terrains, use 3DS Max or external software for that
Requirements

Usage / Tutorial #1
3ds Max : Creating terrain
- Select the plane
- Press "mTerrain" button
- Wait...(progressbar is shown)
- Done, go to Unity..Unity : Getting 3DS Max terrain
- Select your terrain (which has "mTerrain.js" attached)
- Drag mTerrainAsset to mTerrainAsset in inspector window (under mTerrain script, its the terrain height values)
- Note. You can rename "mTerrainAsset" to keep it, new imports are saved again as "mTerrainAsset"
- Press "Update mTerrain"
- Wait...
- Done (your terrain should look like the one in 3DS Max)
- Create plane
- 2000x2000 (same size as your Unity terrain)
- 512x512 segs (Important. 512 in Max is 513 in Unity, so its minus 1, if you use different resolutions)
- Modify your plane to make terrain (for example, add a wave modifier)
- Or use included sample displacement map with displacement modifier
Unity
- Start new project or use your old one
- Add unity terrain to your scene
- Check Terrain / Set resolution.. settings (they must match the values you have used in 3DS Max)
- Add mTerrainObject.js script to your terrain (drag & drop the script to terrain)
After those you can keep modifying the 3ds Max plane and update it in Unity when needed
Go back to 3ds Max
- Modify your plane
- For example: add noise modifier
- Press "mTerrain" button (1 object must be selected when exporting, if nothing is selected, setup window is shown)
Go back to Unity
- Select your terrain
- Press "Update mTerrain" in the inspector
- Note. You need to click "apply materials" in TerrainTools, to get the correct textures in slopes etc.
