"I agree that the teeth in particular suffer in the 2nd pic. I would almost be tempted to render both and then bring them into photoshop for a little "best of both worlds" merging. =)"

In P6, you have the option to render a scene as "shadows only". So, in essence, what you can do is... render the scene one time without AO enabled (all your lights, including diffuse IBL should be on). This pass should render VERY quckly because there's no shadows. Save the image. Then instead of rendering the scene again with AO, you can turn on AO, and just render a shadow pass. This will be an all-white image, save for the darkened areas where shadows are. Then you bring both images into Photoshop, put the shadow pass image above the color image layer, and set the shadow layer to "multiply". Then your shadows are composited over your color layer.

To remove parts of shadows from the scene (like on the teeth for example), simply use the eraser tool on the shadow layer to remove whatever parts you want without affecting the overall effect. Message edited on: 03/26/2005 14:06
