📋 About This Mod

Though not required, it is highly suggested to use this along with Darker Nights

For a better flashlight experience, I also highly suggest Pip-Boy Flashlight

To dynamically control interior fog levels (or remove it entirely) with NO conflicts, grab Dynamic Interior Fog Removal

DESCRIPTION

This mod edits all cell lighting data and templates to make ambient light and fog brightness inside all interiors 60% darker, without touching any directional light sources, keeping lighting 100% true-to-vanilla, except those dark corners and unlit areas.  Subways are actually dark and scary!  This is something I made for myself and have been using, but thought I'd share.  This really lets the directional light sources (i.e. lamps) have a chance to shine (literally!)

This is NOT a post-process filter, a contrast adjustment, or other workaround that effects the overall screen brightness levels like you may have experienced.  Every single interior cell in the game (282 total) has been altered directly to reduce the ambient lighting by 60%, but all placed lights such as candles, lanterns, bulbs, etc are 100% untouched.  A number of common interiors will actually even seem like they're the same, because they are lit really well with direct light sources.  That's the goal, this is just for those unlit areas and dark corners.

If you are familiar with Enhanced Lights and FX Enhancer option for Skyrim, this is the same approach.

The end result is that light feels a lot more realistic, and by cutting out some of the ambient light that Bethesda likes to wash interiors with, the direct lighting has a chance to shine on its own (no pun), and everything has a bit more color, and looks a lot richer.  Opinions may differ, and I'll survive :)

As for the fog, this mod does not remove fog, or "push it away" like some mods, it simply reduces the amount by which light effects the fog.  That is to say, the fog is still there, it's just 60% darker to match the drop in ambient lighting.

This may not be for everyone -- and that's fine! -- I play on a very bright HDTV and made this for myself, and it adds so much that I wish I would have made this before starting my first play through.

DOES THIS CAUSE ANY COMPATIBILITY ISSUES WITH OTHER INTERIOR CELL MODS?

Issues such as the cell reset bug were only persistent in exterior worldspace locations, i.e. Settlements and are not a problem with interiors.  However, there was an issue discovered a couple months back with how the Fallout 4 engine uses precombined meshes, and pre-vis calculations.  These are both g
