occlusion culling and asset bundle

if i use the asset bundle, i find the object’s static tag is lost, why?
does occlusion culling still work?

if i turn on the Cull Gemotry, in scene window i find some object be culled, but the tris in statistics panel don’t change.
how can i know if the occlusion culling work?

thanks.

does anybody know?
thanks.

occlusion culling only exists in the base scene.
you can not import PVS data from streamed scenes.

asset bundles from prefabs etc could not transport PVS data anyway as pvs data is related to scenes, it has nothing to do with the objects at all. PVS does not care what happens to objects after the PVS data was generated btw, so independent on if they are static or not or even there or not, there will be occlusion basing on the positions of static objects at the time of pvs generation

i build all the scene resource as a asset bundle, and at the runtime download and load it.
i don’t change anything after pvs data generation, but the object’s static tag is lost.

it seems in game mode the rendered objects is more than scene mode when enabed the Cull Geometry option.
is it a bug?
