That’s what this system is aiming to fix, but ultimately I still need some help with the material code, because right now it can’t be moved in the projection axis - I’m not great at materials coding, so I haven’t been able to fix this yet.
Perhaps if @Chosker or one of the other artists that have posted in this thread are still interested we could get together and fix up the last bit of the material that needs done (projection axis movement + doing the blood mask properly).
