I made the hair high-poly so it took me a lot of time fixing all the normals... Please let me know if it makes a difference or if you don't really care if it's high-poly or not d=(´▽`)=b
Recommended to have vanilla or upscaled textures on map A. Not recommended to move the hair through metadata because I did not pack the textures in the modpack so they could match whatever texture you use in-game.
