I'm sorry if I seem dense, but could you explain a bit more about that lighting tip, neilp?. None of my LIGHTS have anything on their properties list that implies "include in ray tracing". On the other hand all of my figures and props have a property called "VISIBLE in ray tracing". So, am I missing a special type of light that can NOT be seen in raytracing, because all of mine are by default? I might also suggest an alternative explaination to what might be happening - of course, this is just speculation without seeing the picture in question. Here's what I think is happening. Most commonly available light sets are designed to cast light primarily from the FRONT, and do NOT illuminate the backsides of the objects the way they appear from the front. Remember, in a reflection, you are seeing the side of the prop or figure that you can NOT see from the camera position. If you orbit your camera around the figure by 180 degrees, you might see that from the BACK, there is little or no light, so you need to add a light that shines from the back toward the camera. It won't change the lighting on the front, but it may brighten the ground a little, so you have to balance that. Also note that reflections do NOT reflect the light itself, only things that are illuminated by a regular light. Be sure to orbit your camera back to the front before rendering :-)
