I was still thinking radiosity, with a sky_sphere giving off light.
About the unwanted backdrop-lighting-the-scene problem, I have thought
of two possible solutions :
* backdrop alone in a light_group (but I do not know if this works with
ambient light emmission in radiosity).
* use a no_image, no_reflection clone with ambient -1 (but I fear ugly
lighting artifacts)
Povingly,
Philippe
