Alpha Sorting

Alpha sorting is crucial when using transparent materials. Each triangle is sorted based on distance to the camera. In edit mode the scene view camera is used. In play mode the camera set under Main Settings is used. Alpha sorting can become very expensive with a high triangle count so it can become a performance bottleneck. Therefore it’s only recommended to use this with transparent materials and a moderate triangle count on your groom.

Frustum culling: When enabled triangles that are outside of the camera frustum are culled away. This can doesn’t necessarily give you a performance boost since it requires an extra pass to the culling. Should be used when Apha Sorting is enabled.
