fR-PhysicalSky Texture Map
finalRender R3 offers a physical sky light simulation that accurately models the colors and illumination of the real world sky environment. The light intensities created by the physical sky model are calculated in a true High Dynamic Range format, giving access to the full power of the daylight or sunlight, as we know it from the real world!
The fR-PhysicalSky texture map offers full access to the sky colors created by the skylight model, as well as the sun disc itself.
