I'm not sure if I've shown this one or not, but it demonstrates the power of True Ambience and hopefully points to the potential from PRO-RENDER. This image has more conventional items on show. A poser figure, other meshes, terrains and photo textures. The important point about this pic is that it's lit by just one parallel light (representing the sun). All the other natural fill light comes from True Ambience, and unlike light domes, the light bounces between surfaces like radiosity. In this (reduced size) image there are no problems on show from True Ambience. Any limitations are entirely due to my limited 3D skills. This is completely natural light fill/bounce with pure blacks in the shadows. I'm sure this is what the Bryce programmers had in mind with True Ambience.
