your boy didn't disappear, heres with some new shit for christmas image - Just Another Lighting And Shadow Overhaul mod for Doom

Jalaso doom, a mod made specifically to overhaul certain lighting aspects of doom 1. Certain areas that lack shadows to make the scene more realistic, this mod fixes. Some areas like the first level of doom 1 lack alot of shadows that would appear in modern remakes of this game in different engines. This mod doesn't cheat by modifying the engine in anyway. infact, Jalaso doom will work with any engine port of doom for any machine that supports it, so no additional modification is needed. Shadows and lighting adjustment will be made using in engine tools already available to us.
