Caustics Pass with Alpha

Post by burg » 08 Oct 2011, 15:08

Hey Guys, I'm attempting to render out a Caustics pass with an alpha channel. I have a some nice rainbow colour in the pass and I'm losing that colour in Post when compositing due to the Grid that's receiving caustics being matt blank. Any ideas how I can remedy this?

Thanks
