Natural and Atmospheric Commonwealth (NAC)
is a complete all-in-one DLC sized weather, lighting and visual enhancer for Fallout 4.
From the lighting and the climate to the skin shaders, almost every aesthetic aspects of the game have been altered in some way
to give the most natural and eye candy visual possible.
Because NAC changes so many aspects of the game and because some cannot be made as optional (see description below)
the mod comes as an ESM, like any other DLC, to let anyone chose and modulate which features to keep or not.
*All the pictures from the author's gallery and the description have been made without Enb-Reshade-SweetFX*

F E A T U R E S

to change ingame the climate and season, to use real time season, to enable & disable any weathers and storms,
to change night and interior settings (luminosity, dynamic fog levels), to enable or disable special effects...
It's even possible to shut down NAC climate and weather to only use all other NAC features with another weather mod
or to use the "Hybrid Climate", which allow to have both NAC climate & weather running along with another weather mod.
Click the spoiler below to read more:

Colors, gamma, luminosity, sunlight, sky intensity, exposure, blur, motion blur...you can tweak anything you want.
NACFX can also be very useful to tune a ReShade or an Enb that you feel miss something or doesn't work well in a particular condition.
the NAC's visuals are "neutral" and lossless by default but not meant to be used as is without Enb.

However, if you don't get it then you can also craft it from any chemical bench for free.

<RESET ALL THE SETTINGS>
from the main menu of the holotape.
NAC holotape allows to make safe saves before the uninstall of NAC.
This will prevent crashes with any loaded saves from NAC to another mod or with vanilla game.

NAC Hybride is an optional feature which allow to combine NAC weathers, climate, seasons and lighting features with another weather mod.
Be sure the other mod is loaded after NAC and then enable the Hybrid Climate from the climate section of the holotape.
Then set the priority between the two mods for the weather rotations.
I personally do not recommend using it thought, because NAC does suffice in itself, but the option is here and works fine.
If you only want to use another weather mod but keep all other NAC features then just disable NAC climate from the holotape.
N A C S E A S O N S

The NAC seasons and climate are built-in weather limiters and climate settings
available ingame from the holotape to change the general atmosphere of the game.
Winter is snowy and colder, Spring is rainy and cloudy, Summer is sunny, Fall is foggy and cloudy.
Real-Time automatically loads one of the four seasons based on the ingame month.
Nuclear is a dark, grit and apocalyptic climate. It is the base of inspiration for mods like Moribund World and Pilgrim.
The option to disable/enable any NAC weather from the holotape also gives the possibility to create custom made climates.
N A C & O T H E R M O D S

NAC does a lot of what other mods can do and more,
but in its own way and calibrated for itself, with the insurance of total compatibility and optimization.
Here is a non-exhaustive list of mods that are redundant with NAC and will overwrite NAC changes if used :

TLDR; Any mod for weather, climate, water, time of day, fog, colors, image space & LUTs, interiors & exteriors lighting, godrays, particles, visual effects, timescale... are no longer needed with NAC.
N A C E N H A N C E R ENB

Subtle and optional companion Enb for those who can spare 5 extra fps, NAC Enhancer focus on what cannot be done from NAC:
Additional ambiant occlusion, Various lighting enhancements, Better distant atmospheric fog, Custom Depth of Field
*Compatible bloom for Enb Light Overhaul and Extreme Particles Overhaul by MaxG3D
NAC Enhancer has been made to be used with NACFX.
If you are using the kind of Enb like Vogue or Subtle with NAC,
you'll have much better visuals using NAC enhancer with NAC for the same performance hit.
*: Enb bloom is disabled by default, to enable it just open the enb menu with end key:
Disable "UseOriginalBloom" from the EFFECT tab then click "EnableBloom". Lastly click "Save Configuration" from the upper left corner and close the menu.
I N S T A L L A T I O N:
Please delete any previous Reshade or Enb before installing NAC Enhancer: enbseries andreshade folders, dxgi.dll, enblocal.ini, enbseries.ini, reshade.fx, d3d11.dll, d3dcompiler_46e.dll
1• Download the v0.317 Enb binaries and drop ONLY d3d11.dll and d3dcompiler_46e.dll into the Fallout 4 main folder, where the game's .exe are.
2 • Download manually NAC Enhancer and drop all the files into the Fallout 4 main folder, where the game's .exe and the Enb binaries are.

"NAI": A WORK-IN-PROGRESS INTERIOR OVERHAUL

While NAC only edits light sources, image-spaces and some lighting templates for the interior locations,
NAI goes much further and adds new light sources with reworked interior lighting for all interior cells.
NAI also creates an interior climate using several different weathers types with dynamic sun lighting for all interiors with windows,
using accurate position of the sun depending of the time of the day.
In other words; NAI is NAC but for interiors.
Because it is still in work in progress, some interior locations are performance taxing but optimization will get better as the work will progress.
NAI is stand alone, which means it can be used with or without NAC.
