Hello everyone,
I created this mod for one of my characters and I would recommend using it with my other mod "Face Full of Freckles" (just a suggestion, not mandatory!).
This mod edits the "SKIN_Shared_Shading_MSK" file, which means that other mods using this file are not compatible with this mod. I also want to mention that this mod is not meant to be realistic. So, if you find freckles in places where they might not usually appear, just ignore it or don't download the mod. 🏵️
[This is a reupload. Now you can download the file. I still don't know what the issue was, I've uploaded the same file, but now it works.]
All screenshots were taken with these settings:

Installation:
1. download the file
2. unpack it via WinRar (7-Zip or a similar program) and cut out or copy the "Generated" folder

3. now go to your games directory and copy the "Generated" folder into your "Data" folder

4. Enjoy the game!
Uninstall:
1. delete the "SKIN_Shared_Shading_MSK" file from your "Generated" folder
If you face any problems, please let me now. If you have a request please dm me or leave a comment! :)
