### Remarks

Property `unity_SHAr`, `unity_SHAg`, `unity_SHAb`, `unity_SHBr`, `unity_SHBg`, `unity_SHBb` and `unity_SHC` will be set to zero if they are not part of the MaterialPropertyBlock.

Property `unity_ProbesOcclusion` will be calculated as in normal lighting if it is not part of the MaterialPropertyBlock.

Note that using the light probe values baked at a different place may lead to incorrect rendering, especially when local lights (i.e. point lights and spot lights) are used. This mode is more useful when drawing instanced objects with [Graphics.DrawMeshInstanced](/engine/6000.5/script-reference/unityengine/graphics/drawmeshinstanced.md), where the light probe data is pre-calculated and provided as arrays.
