1 billion thanks to Sal203 for creating this wonderful mod and allowing me to convert the unreleased FO3 version and merge it with the FNV version for use with TTW.
Credits: Sal203 and xCamoLegend for the mods, Roy Batty for fixing the scripts and fixing the issue with the BoS bunker door in New Vegas, Yukichigai for the Fiend of the Night perk fix, and Jax Firehart for the Cateye script fix.
Be sure to visit the original mod pages on the nexus and download+endorse the mods in appreciation!
Use ONIX ENB for the ENB version which was specifically designed for use with RWL by xCamoLegend
If you use ENB, you only need the ENB version, the ONIX ENB preset takes care of the Sun and Night.
The Reduced Sun versions are recommended if you use HDR lighting.
The DC Street (Intro Bus) patch helper is there if you want to use that mod in conjunction. It will fix the map marker placements and is easily merged into the RWL plugin of your choice with FNVEdit (It's only 2 records).
If you liked the original RWL's sun with the lens flare, it is an optional download. Install it after the version you choose and overwrite.
Installation is dead easy with this one, just pick which one you want and install it with your favorite mod manager.
PLACE THE MOD LAST IN YOUR LOAD ORDER, EVEN AFTER MERGE/BASH PATCH
