Cull terrain but not grass and details?

Unity Engine
1

Is there a trick or some undocumented internal function that can cull the terrain without culling the grass and detail objects?

Thanks for any help!

  1. undocumented internal functions are no longer accessable in U3 (at least not on the terrain)
  2. No, detail and grass is part of the terrain either all or nothing shows

And tree meshes fall under this category as well? Just wondering because I know that Unity’s shadow maps render tree shadows but they can’t possibly be rendering the terrain tris for each split

define tree meshes. if you mean the ones painted onto the terrain, then yes.
if you mean meshes you placed in the scene: then they are up to you on when they are hidden and when not (if they are within the view frustum)
