Partly inspired by the younger Astarion mod - which I liked the idea of, but wanted something that would keep more closely to Astarion's vanilla texture, as well as edit the mesh as well. This mod replaces Astarion's face sculpt with one that has been slightly smoothed out, and edits his vanilla textures to have less wrinkles and lines.
It's also important for me to disclaim - I love Vanilla Astarion's face, wrinkles and all. He's such a milf. to me Honestly this was more made because I wanted to imagine what he might've looked like when younger and couldn't truly conjure it in my head without giving myself a visual example and I figured, hey, someone else might like to play with that, too! So there it is. Hope you enjoy, and be sure to let me know if there's any issues! I've dabbled with modding but this is my first time actually posting a mod and not just keeping it for personal use so hopefully all is a-ok.

To install this mod, unzip the file, and place the "Generated" folder into C:\Program Files (x86)\Steam\steamapps\common\Baldur's Gate 3\Data (Windows) or /Users/(User Name)/Library/Application Support/Steam/steamapps/common/Baldurs Gate 3/Baldur's Gate 3.app/Contents/Data (Mac). If you already have previously installed Generated folder mods, merge the folder directory you get from this unzipped file with the directory you already have.
It shouldn't require any other mods to work, but like I said, let me know if any issues arise! Goes without saying, but cannot be used together with any other mods that rewrites the same files (Astarion's face mesh and textures) in the Generated folder, as the game can only read one of those to replace the vanilla assets.
