Occlusion culling with trees on terrain

Am I right that occlusion culling does NOT take into account for trees, that are placed using terrain engine?

Trees are created using Tree Creator and marked as static in prefab + property occludee object…

When trees are placed directly (as object) - culling working…

Another problem with static object and occlusion:
when turn on shadows (defered rendering, soft from one direction light) - Draw Calls count increased…

As I understand shadows does NOT take into account penumbra occlusion culling (only object directly are culled),
and I undestand why (artifacts unavoidable)… However I would like to see options - shadow take into account occlusion pvs…

How occlusion take into account shadows?

Please, clarify.

Thanks!

Anyone know anything? :slight_smile:

Thanks!
