occluders few questions

[demostenes]

Is there any number of occluders in scene, which can be considered counterproductive? Occlusion overhead is only for occluders in frustum, or for whole scene?

 

We have big city with hundreds of buildings, should each building have occluder (for example simple box), or it is better to put occluder only for some? Does anybody have experience with this?

Hi,

It is hard to say without knowing the scene geometry itselft, so the best way to add as more occluders as possible and check the performance changes. The main rule is to hide occluders inside the buildings, not outside, so they would work in more predictable way and will not hide visible in viewing frustum surfaces.

 

You can check our CIty Traffic demo for occluders usage example. Maybe it would be helpful in your case :)

 

Thanks!
