I've just gotten into UV mapping, and I've been wondering: How do skin UVs work? How are they done? How is skin_uvs.png file generated?
In 3D modelling, an object can have different UV Maps. The main one is used for usual textures stuff. The second you add is used by default for skins in BeamNG.drive. https://www.beamng.com/threads/creating-uvs-for-skins.27442/
