This was an absolute scourge on gaming in the 2000s. I remember when gears of war came out on PC and the most popular mod simply removed post processing effects from the game. It instantly went from poop brown to James Cameron Terminator 2 judgement day Blu-ray edition levels of teal.
I think the teal was better TBH.
Remember when uncharted came out on the PS3 and there was a feature in the menu called "Next-Gen mode" that just put a brown filter over everything?
Physics based rendering. Basically good texture shaders that work like materials work in the real world. Since that has been developed artists working with computer graphics in movies and games more or less don't have to worry about making something look realistic.
Every texture has values for color, reflectivity, subsurface scattering, fresnel, roughness and probably a ton more values I forgot. That gives you everything real light does when hitting a surface.
I think Wreck it Ralph was one of the first movies to use the techniques. I remember reading something to that effect alongside tutorials on how to get PBR into Blender. I think it took very little time for PBR to get into basically every graphics software. And nowadays when you buy textures they all come with different textures to set the correct values for PBR.
