Hi, I was recently set dressing a scene when I noticed that upon turning the camera there is a strange visual glitch (sort of a rendering/pre-rendering flicker) that is happening on many of my meshes. Does anyone know what is causing this?
Thankyou!
You can increase a meshes bounds so that it registers earlier in the culling process. This is most likely frustum culling being a little too aggressive.

In depth information regarding fixing culling problems:
Just don’t go overboard with the bounds increase or you will harm your games performance.
Thanks for the quick reply! Unfortunately even when turned up to 10 the flickering is still present, and when set at 2 it is about the same as 1. Is it possible that it’s an issue with meshes intersecting?
Their culling could be interfering with each other. You could try combining the corner walls and see if that maybe reduces the flickering.
Games usually would use more optimized modular meshes with separate interior and exterior meshes. It’s usually good practice to snap meshes to a small enough grid for larger meshes to not intersect if possible.
