### Remarks

Each pixel of this [Cubemap](/engine/6000.5/script-reference/unityengine/cubemap.md) texture is replaced with the cosine-weighted integral of the corresponding hemisphere of incident illumination. In simpler terms texture is nicely blurred.

Can be used to light diffuse object by sampling with its surface normal.
