Occlusion culling
Hi,I have met a problem about Occlusion culling.
My computer is 3G Memory, GTX260. When I using OC with such parameters: cell size(10),near clip plane(0.3),far clip plan(500),only static cull. It crashed when it’s nearly done.The terrain is 720*700,with lots buildings and small geometries and 15 types of unity terrain trees. I have also searched a lot of posts, but still can’t find a good solution.Will 4G memory work? Or where am I wrong?
And even one time I succeed, the result is awful. Not only did it can’t cull correctly what it should cull, but also cull some terrain which shouldn’t be culled.
I’ll be appreciated if someone tell me.
More RAM won’t help, the app is limited to 2GB RAM.
What oyu need to do is limit the cells better (or place them if you avoided that so far).
as for the culling errors: you’ve a cell size of 10, which is pretty large, smaller will help there. also ensure that far and near clip plane are same as the MainCamera in the scene later (though I would recommend 0.01 for the near clip)
The Unity CTO mentioned in one of my posts that the system isn’t very good and they have been completely rewriting it. My suggestion is to forget about playing with it until they release that, you’ll just waste heaps of valuable time trying to make it work.
I’ll say that again, it has been officially stated that it is unstable and is being rewritten…
