So it has GI? Is in this case GI differnet than Radiosity? does the LE Version have radiosity? GI, short for "global illumination", stands for all effects that occur from light transfer between surfaces - color bleeding, caustics, etc (actually, ray traced reflections to also count as global illumination). Radiosity is one method of solving parts of that GI problem, diffuse to diffuse light transfer (radiosity does not simulate caustics, for example). Other algorithms are path tracing or photon mapping, which these days are more popular than radiosity. That said, Shade includes all three algorithms :) Many people say radiosity when they mean global illumination. This misconception unfortunately causes a lot of confusion.
