I have made a little demonstration. It shall prove, that everybody can use only a few Bryce objects in a very simple scene and get quiet good looking results, if only he chooses the lighting carefully.
All the objects, textures and lights are out fo the box from Bryce 7.1. Pro. No modifications are made. (Except the wall which uses a texture I made by myself). The only impressiv difference between the both scenes is the lighting.
The 1. scene uses the Bryce sun, in the way a Bryce novice probably would illuminate the scene. It does not look very convincing, at least not like an indoor scene.
The 2. scene uses no Bryce sun at all, but two additional light sources. A sphere fill light and a parallel light with a gel. With just this simple change you get a far more interesting and a more realistic picture.
