Can anyone tell me why this rock is black? No matter what I do I can not get it to take a light. I have even tried to put the light on the floor right in front of it and it is still black.

Incase you are wondering this is my material setting.

Question: What are you using for the rock? ~DM

Is the rock UV-mapped? If you remove the texture, does it remain dark?

try to inverse the uv of the rock, and/or deactivate the 'remove backfacing polygons' in the render-options. One of these or the combination of both should do it.

A way of doing the "inverse the uv of the rock", is to go to the group edit tool, select the rock (probably only one group, but select all of the groups that apply to the offending area), then click "Invert (or reverse) normals". You should notice in your non-rendered images a very subtle difference from the rock appearing inside out to right side out...

Thanks so much for the help, but nothing worked. The rock is one of the 25 real rocks Yes it is UVMapped This is a picture of some renders The top row is with the Poser 4 render and the rock NOT inverted. The bottom 2 are with FireFly and the Rock IS inverted. All I see that happened by inverting the rock is that it flipped. Not a problem in the picture, because I can always move it back. Just wanted you to see exactly what happened. It looks like the problem is in the shadow. Any idea of how I can fix it?

Goofed on that picture. The last render on the bottom is with the shadow turned on.

What effect are you trying for? It would seem that the rock is no longer black in a few of these. If you're trying to get the rock to cast shadows or the character to cast a shadow onto the rock, you could try changing the material on the rock, using one of the P5 materials and placing something under the rock. You could also try changing your shadow light settings from depth map to ray tracing. I tried playing with this a bit and got much the same result you did when using "cast shadows" in my rendering settings. I think it might be one of those P5 features, but I'm not sure :) I ran out of time to experiment. Maybe there are some P5 experts here who know how to make a perfectly good rock cast a shadow onto something or from a character onto the rock (as I suspect you are trying to do one or both of these)
