Rendering

Lighting

“Other” corridor lighting if the scene is dark or using a corridor the rendering is simpler and easier to do. adding fog is cheaper than having someone do all the map graphics. distance bluing is the same as fogging as distance bluing is more to do with it being farther away.

lens flare is when a light is moving and you pay more attention to the moving light then the other things around you this way you don’t need to put a lot of detail into the things around you.
