📋 About This Mod
Exterior light sources that are off by default will automatically light at dusk, and will be extinguished at dawn. You can also choose to light all cave, and dungeon environments.
Description
Throughout the game, you come across so many light sources that are off by default. It's unfortunate since they often add a lot to the ambiance when lit.
Now, you can make all exterior lights (Cities, towns, etc) across the world turn themselves on at dusk, then turn themselves off at dawn. You'll also have the option to turn on all interior lights (Caves, dungeons, etc) so that they are already lit as you explore these environments.
This mod is mostly for players that just want something lightweight, that want the world to be properly lit, and don't want to be messing around with other lighting mods that require you to constantly be snapping Geralt's fingers to light everything along the path.
