The base class for [PanoramaSky] and [ProceduralSky]. The base class for [PanoramaSky] and [ProceduralSky]. The [Sky]'s radiance map size. The higher the radiance map size, the more detailed the lighting from the [Sky] will be. See [enum RadianceSize] constants for values. [b]Note:[/b] Some hardware will have trouble with higher radiance sizes, especially [constant RADIANCE_SIZE_512] and above. Only use such high values on high-end hardware. Radiance texture size is 32×32 pixels. Radiance texture size is 64×64 pixels. Radiance texture size is 128×128 pixels. Radiance texture size is 256×256 pixels. Radiance texture size is 512×512 pixels. Radiance texture size is 1024×1024 pixels. Radiance texture size is 2048×2048 pixels. Represents the size of the [enum RadianceSize] enum.
