I've been reading with interest the other threads on this subject. I have a scene with a single shadow spotlight representing the sun and some other lights for ambient and fill that don't cast shadows. While I can get the "sun" to cast ray-traced shadows, I cannot get it to cast any shadow at all using depth-mapping. I've already used the shadowcam to tighten up the area so I'm not rendering shadows outside of the view I'm trying to render, and I've increased the shadow map size to 1024, which is bigger than my 640x480 render. "Shadow" parameter is set to 1. In desperation, I copied the entire lighting setup to a basic scene with only a pair of Don and Judy characters positioned so Judy would cast a shadow on Don. I deleted all the other lights except for the shadow spot light. No shadows. I tightened up the shadowcam for that light, still nothing. I switched to ray-traced shadows and there they are, sharp and black. It's like "Cast Shadows" is turned off for everything in the scene when I try to use depth-mapped shadows. Any ideas?
