Thought I’d share this script, Unity does frustum culling based on each renderers bounds and the cameras field of view, near and far clipping planes. This little script, attached to a camera, let’s you preview that camera’s culling in the Scene View, useful for optimizing and debugging your levels.
#UnityTips – Preview Frustum Culling
[UPDATE: Handles multiple scene views better and doesn’t spam errors when there’s no scene view]
[UPDATE: Fixed editor text field inputs not working when preview was enabled]
