By the way, i didn't finish the end cinematics yet. My question is in the boss cinematic without Arthas. Type 'BossM' in the game. In my computer, it crashes when i wanted to go there. Does it crash in yours?
I'd like to understand this better. In my experience, I always had to depend on a "color swap" tool being available, which is nice (seems simpler than your method), but imprecise (have to be very careful to select the write parts & not draw over anything else). Also, it seems to rob it of some of the shading & subtle nuance.
