Back in 2018, we informed you about the Fallout 4 Ultra Interior Lighting mod. This mod brought lots of shadow lights and a general improvement to overall lighting, ambience and fog to the interiors of the Commonweatlh, Far Harbor and Nuka World. And today, modder Gargorias released a similar mod for the game’s exterior environments.
The Fallout 4 Ultra Exterior Lighting mod adds shadow cast lights to numerous physical light sources in the exterior world. This includes places like Far Harbor and Nukaworld. The modder has also made vast improvements made to the general lighting associated with physical lights sources. Therefore, the overall lighting is way better than before, providing a vastly more immersive exterior lighting.
Going into more details, the mod enhances around 1500+ physical lights. All these physical lights now have shadow cast lights for them in place of the non-shadow cast ones.
Furthermore, almost all the new shadow casts lights use a trigger box that swaps them to their non-shadow cast version at X distance from player depending on the location and other factors.
As the modder noted, the use of trigger lights allows for better distance lighting and helps improve the performance. This is achieved by not having the shadows rendered where they are not really visible.
This mod will noticeably improve the visuals of Fallout 4, so we strongly suggest downloading it from here.
Lastly, we also suggest checking out the Fallout 4 Wasteland Illumination Mod that adds 1380 lights to 763 light sources in Boston Commonwealth. Moreover, there is another Fallout 4 mod that adds dynamic lights that cast realistic dynamic shadows in exterior places. Do note, however, that these mods may not be compatible with the Fallout 4 Ultra Exterior Lighting mod.
