The surface texture of the default reflection probe that captures the environment contribution. Read only.
Unity maps this texture onto the surface of the default reflection probe.
The SkyManager automatically generates the default reflection probe to capture environment lighting.
To disable the environment contribution in the lighting result for a scene or GameObject that does not have manually created light maps and Light Probes, disable the default Reflection Probe and the Ambient Probe. For more information, see Disabling the SkyManager.
