Gary I am uploading a file (shadows.3ds) in the project/meshes area that I am having a major problem with. The shadows are complete on frame 191 and truncated on 192. This happens with both ray traced shadows and shadow mapped shadows. It is a small part of a major architectural problem and I am tearing my hair out trying to solve it. Any help would be appreciated. Alan

On large scenes, if the geometry size changes dramatically, the shadow bias calculation can make shadows appear and disappear. Try setting the following in your 3DS.SET file: SHADOW-BIAS-ABSOLUTE = ON Note: You may have to experiment with new shadow bias settings. – Dave
