Sets the method for generating the radiance map from the sky. The radiance map is a cubemap with increasingly blurry versions of the sky corresponding to different levels of roughness. Radiance maps can be expensive to calculate. See [enum ProcessMode] for options.

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.

Uses the fast filtering algorithm to process the radiance map. In general this results in lower quality, but substantially faster run times.
[b]Note:[/b] The fast filtering algorithm is limited to 128x128 cubemaps, so [member radiance_size] must be set to [constant RADIANCE_SIZE_128].
