I’m coming to the conclusion that the shapes used for the remove tool should be rather loose, but also using as few shapes as possible.
I’m having a similar issue as the original post. I’m doing a fg roto of a women and I’m creating simple shapes for the head, neck, arms etc.
I group up my shapes for the fg women, and in while in the remove module I have the gear turned on for all shapes in the layer menu to be removed. It works, but if any shapes overlap, it subtracts from the matte it’s overlapping and there is no removal in that area. I looked into the join shapes tool, but that seems for corners on walls and floors and such. The shapes points attach to one another. This seems for an entirely different situation.
So really, you need to do one shape, or multiple shapes and render in passes correct? Seems a bit odd.
I’m also noticing that when you have multiple shapes in one later, they also subtract at the intersection and it doesn’t seem to be any way to change that behavior.
I’ve come to the conclusion that all shapes should get their own layer when doing shapes for roto. You can add shapes to a layer for simple garbage mask type situations where shapes don’t typically overlap or you can join the edges of simple shapes. Would you say that is correct as well?
Thanks for your time
