input | Array of float values to be used for Realtime GI environment lighting. |
Allows overriding the distant environment lighting for Realtime GI, without changing the Skybox Material.
The input array represents a cube with each face being 8 x 8 texels and each texel being 4 floats (for the RGBA values of the texel's color), so the size of the array is 8*8*6*4 = 1536 floats.
Note that changing the Distant Environment Lighting Source or Environment Lighting Intensity will overwrite the data set with this function.
