Hi there, I have a problem that I remember having in the past but I forgot the solution. I had a 6 year break with 3D animation...
I set up my scene with the new render layer setup. I created a shadow pass and added all lights and geometry needed. then I created a shader override using a background color shader to render the shadows.
What I get is a hard edge on my geometry (see attached image).
the lights are setup a typical 3 spotlight fashion. Main, brighten and counter light. Only the main spotlight is casting a shadow (KISS).
I fiddled with the normals, the uv mapping the background shader settings (no reflection, no specular) and the render settings. Softening the normals sort of moves the hard edge, but doesn't eliminate it. The only thing that cures the hard edge is moving the light up. But I cannot do that as it would change the entire lighting of the scene...
