| [BlendProbes](/engine/6000.6/script-reference/unityengine/rendering/lightprobeusage/blendprobes.md)       | Simple light probe interpolation is used.                                                                 |
| [CustomProvided](/engine/6000.6/script-reference/unityengine/rendering/lightprobeusage/customprovided.md) | The light probe shader uniform values are extracted from the material property block set on the renderer. |
| [Off](/engine/6000.6/script-reference/unityengine/rendering/lightprobeusage/off.md)                       | Light Probes are not used. The Scene's ambient probe is provided to the shader.                           |
| [UseProxyVolume](/engine/6000.6/script-reference/unityengine/rendering/lightprobeusage/useproxyvolume.md) | Uses a 3D grid of interpolated light probes.                                                              |
