Perfect Culling - Occlusion Culling System

Perfect Culling enables you to bake pixel perfect occlusion data for prefabs and your scene.

It works by assigning unique colors to all renderers and taking pictures from multiple perspectives. At the end the colors found in the images allow the asset to tell whether a renderer was visible or not.
 

You can take a break while Perfect Culling does all the hard work for you. You will come back to pixel perfect occlusion culling data with little to no performance overhead at runtime.
