This second image is rendered with normal settings. Rendertime 6 seconds. The settings on the HDRI sphere are the same. 100 diffuse, 100 ambient, both diffusion and ambience driven by the picture in channel A. There's so big a difference? But I don't understand why, having sunlight disabled in both images (both, I repeat, have the same settings), I see perfectly even when I don't use True Ambience. Please forgive me if this is trivial, but... anyone can enligthen ;-) me about this? Thanx in advance, Stefano
