Greetings I have a person’s head that I’m putting a light wrap on but I only want it on part of the head. I then want to further limit the light wrap, using the roto from background wall/window opening.
Should I be creating a roto node first for the region I want the light wrap to stay within, then pass that roto into the light wrap node input, then use a Composite 1 node to input the light wrap node as foreground and the original person’s head as the background, and then send this output to the background of a second Composite node 2 with the wall/window roto as the foreground, or is there another better/recommended way for doing this? Thanks for help on this
Also just to mention a problem I’m having, which I think is related to the light wrap. I tried to comp just a small roto circle of the original head on top of Composite 2, using a Composite 3 where the roto circle is foreground and the Composite 2 is background, and I noticed that there’s what looks like a 1 pixel border around the roto circle. I was expecting it to be a perfect blend from the output of Composite 3, and if I add some blur to the roto circle, it does remove the hard 1 pixel circle edge, but it also seems to create a black/empty space around the circle, which now make a weird dark circle on the final head where the roto circle is
