I have a live action video texture of a figure (on green-screen) that I am projecting onto a panel and using the alpha channel created in Premiere to mask out the panel so that the figure now appears to be on a virtual set. The problem is that the edge of the alpha mask has a dark outline that does not appear in the video file (see attached). It’s more noticeable when the figure moves, as the outline undulates around it - particularly in the hair.
I thought this might be an artifact from Premiere so I re-exported the color channel with a matching color background behind the figure (i.e. matching the virtual set), but now it’s a glowing highlight instead of a black outline (see attached).
I’m sure it must be a simple settings issue in the materials editor since I always get flawless alpha channels out of Cinema.
Thanks.
