Turn Bounding Mesh On or Off

In the 3D world, each object has its own bounding mesh, which is a box that identifies the XYZ ranges of the object. You may decide to turn it on or off after you convert the object to be part of the terrain. Then you may move objects or plant vegetation over the mesh itself or the bounding mesh that surrounds it.

The Difference between On and OFF

In the 3D Viewer Control bar, switch the mode to Snap to Terrain or Follow Terrain.
Apply one prop (Pyramid) to the project. Right-click on it and select Add to Terrain.

In the Scene Manager, pick the prop under the Terrain entry.
Go to the Terrain Component section of the Modify page. Uncheck the Use Bounding Mesh box.
Apply another prop (Sphinx) and drag across the terrain to see the result.
Check the Use Bounding Mesh box. Drag the prop across it again and see the different result.


Use Bounding Mesh = OFF	Use Bounding Mesh = ON

Note:
To examine the bounding mesh of a prop before adding it to the Terrain, go to the Scene Manager and change the setting from Normal to Bounding Mesh. You can also Right Click on the prop and choose Display then set the Render State to Bounding Mesh.

Why Turn Bounding Mesh On?

This feature is useful if you want to utilize the Follow Terrain or Snap to Terrain function in iClone. It avoids your objects from twitching as they are crossing a complicated but small fold of the terrain components.
