Here’s what I’ve got so far on the mod: Fatroll New Vegas: Weight Gain Mod Demo by failmuseum on DeviantArt
How to install:
First you need the CBBE body for FNV installed correctly BEFORE you install my mod. The page explaining this process can be found here: https://www.loverslab.com/topic/91919-fonv-cbbe-bodyslide-port-alpha-update-18-mar-2018/ Technically you don’t NEED to do this, but your nude body suits will have odd textures and I don’t know what happens if you don’t install the skeleton. Also DO NOT batch build, only “build” the CBBE base/nude body with the “fed” preset.
Once you have that working properly, simply install my mod using a mod manager of you choice (it should work like any other mod. If it doesn’t, a manual installation will work for certain). Any time you are asked if you want to replace a file, just say yes (this is the reason you want the cbbe/bodyslide mod installed first).
Oh and one more thing, I don’t recall if I set all of the food item’s weight gain values again. I know I did for the casseroles and Nuka Cola for certain though. Use those if your food items aren’t causing any weight gain.
