The Built-In Render Pipeline is deprecated and will be made obsolete in a future release.
It remains supported, including bug fixes and maintenance, through the full Unity 6.7 LTS lifecycle.
For more information on migration, refer to Migrating from the Built-In Render Pipeline to the Universal Render Pipeline and Render pipeline feature comparison.
Most of the Renderer components in Unity contain Light Probes. There are three options for Light Probes:
  • Off: the Renderer doesn’t use any interpolated Light Probes.
  • Blend Probes (default value): the Renderer uses one interpolated Light Probe.
  • Use Proxy Volume: the Renderer uses a 3D grid of interpolated Light Probes.
When you set the Light Probes property in the
Mesh Renderer

?

component to Use Proxy Volume, the GameObject must have a
Light Probe Proxy Volume

?

(LPPV) component attached. You can add a LPPV component on the same GameObject, or you can use (borrow) a LPPV component from another GameObject using the Proxy Volume Override property. If Unity cannot find a LPPV component in the current GameObject or in the Proxy Volume Override GameObject, a warning message is displayed at the bottom of the Renderer.

Example

An example of a simple Mesh Renderer using a Light Probe Proxy Volume component

In the Scene above, there are two planes on the floor using Materials that emit a lot of light. Note that:
  • The ambient light changes across the geometry when using a LPPV component. Use one interpolated Light Probe to create a constant color on each side of the geometry.
  • The geometry doesn’t use static lightmaps, and the spheres represent interpolated Light Probes. They are part of the Gizmo Renderer.
