Wow, a real blast from the past. Proves that ebots will haunt you forever. "We were able to make light bounce with TA, but since there are no TA LIGHTS, per se, it is nearly useless as a tool..." While TA can't help in bouncing hard light off of mirrors, it is far from useless. It "bounces" diffuse light quite well, and in this context all Bryce lights are "TA lights" since they can all provide the initial "energy". True Ambience was only partially developed when Bryce5 was released, and there are quite a few problems with how various objects and surfaces react to it (non-smoothed polygon meshes being notorious). If DAZ can fix those (or some) for Bryce5.5, then True Ambience may see more action. "who I consider a "heavyweight", regardless" If you're calling me a fat git - you're right.
