I have this odd problem with fur. I am using render layers, and have split my grass (fur) into a render layer of its own. The problem is that the tips seem to take on the colour of the camera background. How can I make it so that it is just transparent? I need to get rid of the background color otherwise I can't composite. I attach a psd in a zip so you can see what I mean.
