raytracing problem
ive textured a model, set up a 3 point light rig, and turned on raytrace to get some nice shadows. this all works fine, until i add a bump map to the texture. the light seems to pass through the dark areas created by the bump and show up on another part of the model. can someone help explain whats going wrong.

one, make sure you didn't accidentally drop the bump map image into the transparency node, and 2nd, make sure your bump map image didn't have an alpha channel built in.
Accept no substitutions.

jpeg: you're fine it doesn't contain an alpha channel.
tiff or targa: to be sure check the image in photoshop or any compositing software.
sometimes the viewer in your operating system (win or mac or whatever) will show you the image cut out. other wise you will have a nice rectangular image...
maybe this could be the answer to your other question... *shrug*
