fucking
karin lmao
took me waaaaay longer than I expected
for anyone that cares, the issue is that having any kind of texture in that stage causes bounce lighting which shows up on the character models, sort of like a fog. So using the typical chroma key green means that it's super easy to cut out the characters... but they're all green tinged.
using white creates a fog over everything
using NO textures fixes that, but photoshop isn't clever enough to distinguish between black on clothes and the black of the scene.
so for characters with black clothes I have to use this sort of middling grey colour which doesn't cause much bounce lighting but is also at the same sort of shade as a lot of midtones on characters... so they become much harder to cut out (like Karin)
hope that was interesting for someone. If I could find a way to turn off bounce lighting it would be perfect...
