Hi Guys, can someone point out the best practice to optimize culling? See the current cull volume setting on the right, and the effect via game view.
Somehow there is always a gap between different LOD's, same for the materials.

Should I use mesh cull settings too, or is there a recipe for the right cull volume settings? Or do I have to adjust mesh LOD settings as well?
Notice also that I use auto generated HLODs, but those doesn't seem to affect the current structure culls.
