I have yet another technical problem, sorry.

I'm rendering out a beast for a scene in a fan film. It will be put together in compositing. So the backdrop, the shadow, the AO on the ground and the Animal are all rendered on separate layers.

The animal is rendered on his own with a straight alpha channel (so it adds some similar pixels around the edge).

He needs a plane under his feet for clipping but mainly for the AO on the bottom of him. But it is composited black.

I don't mind it shows up in the render as it's not on the alpha channel, so disappears in compositing. It's visible as i used some environment fog.

Unlike the white lines that got slapped round his feet (by the straight alpha pass) at the end of each frames render?!

Does anyone know a work round for this?

Sometimes it happen if the scene have special filters into render setting. Did you used color mapping or something else?

No but i did use environment fog..

Hi Mikeb,
did you tried to use a pure black material for the plane under the animal in C4D? the shadows and AO will rendered however.
