Thanks Wayne, that will get me the end result I'm looking for. I was just looking for a way to do it in my default color pass, but whats one more pass...

Hey Karl,
Make a new pass and apply a white constant to the objects that are behind your fence. Apply a black constant to your fence and then render. Or vice versa. Black back, white fence. Use that as your alpha for selection/masking purposes etc. At least I think this is what you were meaning you wanted.

Sorry Wayne for the late response, been real busy. I'm not sure what you mean by "apply a matte". How would one do that?

Karl.

I have a chain link fence texture with alpha transparency. The problem is when I render I see the objects behind the fence in the fence render layer. Can anyone tell me how I can render out the fence so that I'm left with an alpha channel between the fence wire?


Cheers, Karl.
