The Light Probe Proxy Volume component offers the possibility to use higher resolution lighting for large non-static GameObjects.
By default, a probe-lit Renderer receives lighting from a single Light Probe that is interpolated from the surrounding Light Probes in the Scene. Because of this, GameObjects have constant ambient lighting regardless of their position on the surface. The light has have a rotational gradient because it's using spherical harmonics, but it lacks a spatial gradient. This is more noticeable on larger GameObjects and Particle Systems. The lighting across the GameObject matches the lighting at the anchor point, and if the GameObject straddles a lighting gradient, parts of the GameObject will look incorrect.
This component will generate a 3D grid of interpolated Light Probes inside a bounding volume. The resolution of the grid can be user-specified. The spherical harmonics coefficients of the interpolated Light Probes are updated into 3D textures, which are sampled at render time to compute the contribution to the diffuse ambient lighting. This adds a spatial gradient to probe-lit GameObjects.
