Hello, I have these colored glass shapes in my scene with nothing else but lights and a white floor and white cyc wall. My renders look good with caustics creating colored shadows or reflections on the white floor. My problem is my floor and cyc wall have lots of natural gradient shadows but my client wants the glass shapes to be in a all white environment (think The Construct from The Matrix).
What is the best approach to achieve this? I thought maybe I could composite the shapes and shadows separately on a solid white but I can't seem to just get the shadows from the shapes. I tried all the AOV's; specular AOV with shapes primary visibility turned off gets me the colored shadows but also all the gradient shadows as well. aiShadowMatte just gives me an alpha for all shadows.
Perhaps there is a way I could achieve this look solely in Maya?
