I have finally made shadows work thanks to Daryll Strauss's example RIBs. However, it *still* wasn't as easy as it should be. I followed the format of his examples but my shadows kept ending up in the wrong place and I kept getting a strange vertical shadow on the righthand side. It was driving me crazy. Anyway, while playing around with 3DReality, I noticed in the Help section on creating Textures that your image has to have a pixel size that is a power of 2! (Is this documented *anywhere* else?). Anyway, my image was being rendered at 600x600 which caused all the mess. I changed it to 512x512 and everything works dandy now. I hope this helps someone (I can't be the *only* dunce that couldn't figure this out, could I?? :-) ambi
