Light Probe Panel

From the top menu of the editor, select Projects -> Light Baking -> Light Probe to open the Light Probe Baking Panel.

The Light Baking Panel will bake the light-probe already laid out in the Scene Editor. After baking, the indirect light information of the static object will be recorded to the storage medium; all nodes configured with the Movable property will have access to more detailed and realistic indirect light effects.

PropertiesDescription
GIScaleGI(Global Illumination)scale factor
GISampleGI sample count of each light probe
BouncesNumber of light bounces, in the range [1, 4]
The meaning of bounce is the process of the current light source hitting an object and bouncing back to the probe.
If the number of light bounces exceeds this property, it will not be recorded in the baking result
Reduceing RingingIn some cases, the light from the light probe may penetrate from bright to dark areas thus forming a ring. Modifying this property may improve the situation, but may result in unrealistic lighting
