ENB compatibility?? Yes!
This is not strictly for ATMOS Enb, so far I tested with Enb Next Generation and The ENB of the Apocalypse.
BUT you must use same interior lighting settings in enbseries.ini as ATMOS Enb.
LightingIntensityInterior=0. 62
LightingCurveInterior=1. 0
AmbientLightingIntensityInterior=0. 72
AmbientLightingCurveInterior=1. 1
LightingDesaturation Interior=0. 0
AmbientLightingDesaturation Interior=0. 35
FogColorMultiplierInterior=0. 75
FogColorCurveInterior=1. 27
Performance hit?
Practically none for modern systems. Interiors now have twice the amount of lighting nodes, but these are simple non shadow-casting vertex nodes.
Some interiors still look off?
Yes, this isn't universal for all the cells. All effected cells are handcrafted and take around 1 hours each. Thus I chose a select few cells which looked bad and are relevant in most playthroughs.
Below some examples of my finest work

✨ Key Features
📊 Pros & Cons
✅ Pros
- Community-approved with 144 endorsements and over 6.5k downloads
- Hand-crafted lighting gives a unique, artisanal feel
- Pitch black environments add real tension to dungeons
⚠️ Cons
- Pitch black might be too dark for some players, making navigation frustrating
- No screenshots or videos provided, so you can't preview the effect before installing
- No compatibility notes with other lighting mods like ELFX or Relighting Skyrim
For Skyrim players who want a more atmospheric and immersive interior lighting experience, especially those who enjoy darker, more realistic dungeons. Skip if you prefer bright, fantasy-style lighting or if you rely on other lighting overhauls that might conflict.
💡 Beginner Tips
- If you're using a mod manager like Vortex or MO2, install this mod and let it overwrite other lighting mods to avoid conflicts.
- Test in a dark dungeon like Bleak Falls Barrow to see if the pitch black is too intense; if so, look for a lighter version or adjust your brightness settings.
- Since this mod only affects interiors, you can combine it with exterior lighting mods without issues.
