I have rendered a BW image (a logo) using an Emission node that I would like to use as an Alpha Mask for a specific color (it’s a decal).
So in Compositor I made a Set Alpha-node where I put the desired color. In the Alpha-input I put the rendered BW image. When I check the result in Compositor, it looks great, but as soon as I render I get a white fringe around the render (???). Can anybody please help me out here?
Many thanks in advance!
