I’m working on a project using cycles. My current scene has static geometry and camera movement.
I takes 30 seconds to 1 minute to create the BVH depending on the scene, but often only a second to render it.
So, I tried the Cache BVH feature.
However, it isn’t working at all. It rebuilds the BVH every single frame… so instead of rendering in minutes, I’ve got to wait hours for my scenes to complete.
If this feature worked, it could save me 20 hours of render time.
Does this feature work for anybody else? Maybe I’m just not doing it right.
