I am also interested in faking radiosity. Think we need more studies in that field ; for instance, we could try to use only indirect light (for example spot lights hiting plate target covered by a picture, light ray being redirected on the object viewed by the camera). Another point, if using direct light, is to use only soften light. Also add blured reflection on all the object (10, even with very low level of reflection). But all this is experimental , and maybe depend on the scene we create... Yves
