Title: the transparency on alpha channel
Post by: Arzillo on 2024-10-01, 10:51:52
Hi everyone, how do you put transparency in the alpha channel of the glass? In practice, the alpha channel of the glass should not be a precise contour of the glass, but should allow you to see the transparency to be used in post production

Hi, you should use "mask propagation" for this:
