📋 About This Mod
I tried to fit Heather here into the impression I got of her as some independent girl, that is foolhardy, yet with a day-dreamy personality.
There's 4 hairstyle versions for you to choose from (see pics for reference)
Also for those that may be wondering why the 4th version is her having dark blonde hair, that's actually my initial concept appearance for Heather but then I realized literally all the other FO4 female companions have dark hair already. So I made her blonde later on for the sake of diversity :)
The last thing I ever want is my NPC designs to have the same faces..
REQUIREMENTS (your load order should follow this way too!):
- Heather Casdin, duh
- Femshipping conversions
- Real HD faces - main file + Real HD faces- textures (this specific mod is optional but you MUST still use 2K face texture mod of some kind)
- Eyes of Beauty
- Kirs freckles 2K vers
- Appealing moles 2K vers
- Looks Menu Customization Compendium, (AND *LMCC face textures 2K vers)
INSTALLATION:
- Choose between 4 ESPs for the hairstyle. Either way, you can change her hairstyle yourself anytime you want in-game via the slm command.
- Presets are already included alongside the ESP replacers!
- I have not tested out the ESP replacers themselves (since my new game keeps crashing with 700+ mods argh) so if you're having issues with the ESP replacer, just use the 'slm' command in-game on Heather and use the preset instead.
