Alpha channel render

#1

I have a set of color frames with no alpha channel
and another set of B&W-frames with no alpha channels

I want to use the B&W frames as the alpha for the color frames.

Is there a way to render out a set of frames(color) to targas but when saving have it embed the B&W frames as the alpha channel.

please help, your my only hope:sad:

You can use any tool that mix or copy channels, in this case copy the luminance from BW frames to alpha channel of colored frames

Thanks. I tried to figure out how to do what your saying but haven’t found a way yet. I’m using DFX+ 4, so it may not have that function. I did find a way to kinda do what I wanted using a bitmap mask. I tried it once before and I couldn’t get it to work, geuss I had it setup wrong. I still can’t get the new alpha or luminance channel to save as an alpha. I keep tryn, thanks again.

Have you tried using channel booleans?
