Description

Stores light probe data for all currently loaded Scenes.

The data includes: probe positions, Spherical Harmonics (SH) coefficients and the tetrahedral tessellation.

You can modify the coefficients and update the tetrahedral tessellation at runtime. You can also swap the entire LightProbes object for a different pre-baked one using LightmapSettings.lightProbes.

See Also: Light Probes in the Unity Manual, LightmapSettings, ReceiveGI.

Properties

bakedProbesCoefficients of baked light probes.
cellCountThe number of cells space is divided into (Read Only).
countThe number of light probes (Read Only).
positionsPositions of the baked light probes (Read Only).

Static Methods

CalculateInterpolatedLightAndOcclusionProbesCalculate light probes and occlusion probes at the given world space positions.
GetInterpolatedProbeReturns an interpolated probe for the given position for both real-time and baked light probes combined.
TetrahedralizeSynchronously tetrahedralize the currently loaded LightProbe positions.
TetrahedralizeAsyncAsynchronously tetrahedralize all currently loaded LightProbe positions.

Events

lightProbesUpdatedUnity raises this event to indicate that the light probe structure (tetrahedralization) or values (spherical harmonics coefficients) have changed.
needsRetetrahedralizationAn event which is called when the number of currently loaded light probes changes due to additive scene loading or unloading.
tetrahedralizationCompletedEvent which is called after LightProbes.Tetrahedralize or LightProbes.TetrahedralizeAsync has finished computing a tetrahedralization.
