Vault-Tec Workshop Overhaul is a mod that makes changes to three of the main lighting issues in the Vault-Tec Workshop DLC: brightness, lighting node positions, and the bug that caused lights that were on to appear off.

Vault-Tec Workshop Overhaul makes the lighting more realistic. The lighting now projects from the correct location, which helps to make the scene more believable. The lighting also looks more like the lighting in real life.

In addition, it fixes the bug that caused the lights to appear off in the Vault. This bug was fixed by changing the value of a single lighting node.

The lighting bug was one of the major things that made the scene less believable. The way the light was projected from the atrium, and the way the light was distributed throughout the Workshop, was no longer the way it was in the original version of the game.
