Hi! So, this question is more about GTA V, but there's no modding topic for V.
I've noticed while checking on V textures that there's two different kinds of normal maps. Blue ones and yellow ones. The most used, almost for everything, are the yellow ones, and it seems to be for optimization reasons, because of consoles and stuff... Or I assume, I'm not sure.
IV always always used the blue normal maps, or at least the PC version did. Does anyone know the difference between these normal maps? Is the yellow one used because it's better or something?
