We tried postprocess volume for interiors, but that’s not a natural effect, expecially in a running game.
You walk across a door and what? Turning exposure down? This would make you look outdoor and see everything dark, and it wouldn’t be a smooth transition. To smooth it we should use the blend radius and you would see lighting turning off before entering a palace for example.
I don’t think post processes are not a solution, I simply believe that it’s a forced one and not the best
