There is a mask error on the tube on the top right corner(triangular shape) in your pic.

Amazing job on this one, good riddance matte lines :D

It's ok, it's after effects being a shit. There isn't even a mask created in that area, especially that shape so i don't know how that section is missing. It's only on that screengrab on that one frame, but i'm pretty sure it's not in the full render. I'm having all sorts of hell with after effects recently, so i'm usually having to render everything a few times. I need to wipe the drive and reinstall everything soon, but i'm trying to put it off until i've finished ESB:R
