Hello,
I have a shot where there's a 3 dimensional object and have geo for it to hold out the layers of dust and debris. The problem is the geo isn't perfectly accurate to what is in the plate. But I have 2d roto that perfect.
The problem: using deep hold out how can I use 2d roto to basically reproject and properly hold out the different depths? I know I can do this with like a 2d car if it's a simple holdout, but how can I do it if it's a holdout that has 3 dimentions?
The issue: idk how to project that 2d roto on 3d geometry, and even if I did that, the 3d geometry isn't accurate like mentioned before so it would cut off my roto in areas,bits like the 3d geometry would need to be eroded in 3d space to account for that lol but idk if that kind of thing is even possible.
Thanks for any help!
