Hi there,
So I’m working on a little city builder to gain skills on Unity and other things. Right now I’m facing a performance issue as the latest asset I added has too much tris (12,300 in blender).
I’m working on it actually but I figured that I could also improve performances by using occlusion culling. However, default Unity OC works with baked data which is not really compatible with a city builder.
Is there any way to make it works with dynamic environnements?
You should look this over: Unity - Manual: Occlusion culling
And what? Thx but I already did.
Occlusion culling is already enabled on my main camera, my assets renderers have Dynamic occlusion enabled but the scene is empty on a new game so no bake datas nor Occluder.
To be more precise, what I need is a way to make my assets act as occluders even if it wasn’t in the scene when the game is loaded
You cannot. Unity’s occlusion culling solution needs to be baked at edit time, you cannot add occluders at run time.
Also, city builders often use overhead views which don’t benefit from occlusion culling. What do your game look like?
Free camera, overhead view… so as you say, it will probably not benefit from occlusion culling. So I guess, I’ll have to make with fustrum culling only and simplify my models as much as I can
