Normal behavior, I do maps the same way and copy back and overwrite all changes. Helps me stay sharp.
It's reassuring ! And just to complet my question, do you also have to modify the path in some material.cs while creating or editing some textures ? I have some path going like : BeamNG/content/levels/map/art/ etc... Just have to delete everything before the /level/ but once more, is it normal ? Thanks guys !
Yes that is normal too ( in my world anyway ). Changing filepaths created by the material save in documents is like breathing air now.
