Detail Meshes


Any Terrain decoration that is not trees or grass should be created as a Detail Mesh. This is perfect for things like rocks, 3D shrubbery, or other static items. To add these, use the Paint Foliage button . Then choose Edit Details button->Add Detail Mesh. You will see the Add Detail Mesh dialog appear.

Painting Detail Meshes

Painting a Detail mesh works the same as painting textures, trees, or grass. Select the Detail you want to paint, and paint right onto the Terrain in the Scene View.

Painting Detail meshes is very simple

Note: When you have a brush selected, move your mouse over the Terrain in the Scene View and press F. This will center the Scene View over the mouse pointer position and automatically zoom in to the Brush Size distance. This is the quickest & easiest way to navigate around your Terrain while creating it.

Editing Details

To change any import parameters for a Detail Mesh, select it and choose Edit Details button->Edit. You will then see the Edit Detail Mesh dialog appear, and be able to adjust the parameters described above.

Refreshing Source Assets

If you make any updates to your Detail Mesh asset source file, it must be manually re-imported into the Terrain. To do this, use Terrain->Refresh Tree and Detail Prototypes. This is done after you've changed your source asset and saved it, and will refresh the Detail Meshes in your Terrain immediately.


  • The UVs of the detail mesh objects need to be in the 0-1 range because all the separate textures used for all the detail meshes are packed into a single texture atlas.
