Greenscreen as image mask.
Hello! I've been trying to try some different techniques I could do in animation and I wanted to try adding irises in video editing process. To do that, I wanted to make green screen sclera to act as a mask for eye. Yet, as you can see in picture below I had ran into number of issues.
The eye clips on top of the character, as well as whenever I apply set matte, the transparency disappears. Mask didn't seem to help either.
Does anyone has ideas on how I could fix this? Or are there any other methods I should try doing for these kinds of things? I can edit the colour of sclera no problem in the software I use. The iris is a separate png I did in Photoshop, but if I need to export it in different format I also can do so.
