Occlusion culling Problems

Unity Engine
1

Hello,

I need some help, if someone could have a look to my project.

I am building a virtual museum for a french institution, with many movies and photo…

But i have some problems with the occlusion culling

I have experimented many settings (big occlusion area, differents occlusion area), and I have objects that disappear, and i don’t know why…
Maybe because the trees, but i am not sure…
Here are some snapshots of my project

The Occlusion Culling settings are:
View cell size 10 (If I put a lower setting, it is very long to bake, and it is worse)
Near Clip Plane 0.01
far clip Plane 600
Bake Quality “Production”.

Maybe someone could have time to help me to build a good occlusion culling… ?

Thanks

Yann

All the architecture is done with C4D,

and is imported as an single object set in static

Other objects are groups under empty objects by localisation in the different rooms of the museum

Here is the inspector for the occlusion area box

the Occlusion Culling
They are no target.
Some objects disappear

The occlusion culling area.
I set it like that, without the garden and terrain in the front, because the garden disappear when i put it in the occlusion culling area

OC is now very buggy and unstable. UT claimed, that they are completly rewriting its implementation.

Argh… thanks for your quick answer…

but… in my project, it is not far from working correctly… the moves are really much more fluids with occlusion culling…
I think it is just a little setting hidden somewhere I should do…

Ok, I find the solution…

It is the trees… if I make a Bake of the occlusion culling with trees disactivated, it works fine.
I just have to reactivate the trees after the baking.

Hope that help

Painted trees, or individual meshes?
