sometimes I just want to bulk edit the second uv layer in blender, which is normally the skin layer. Switching it individually was annoying, but I couldn't find any info on how to do it (maybe I'm just bad at google), so I wrote this handy dandy little plugin (mostly piecemeal'd from examples I could find) to just switch all selected layers. Select all objects you want, and in the 3D Viewport, in Object Mode, go to Objects, then at the bottom "Switch to Second UV Layer" or "Switches selected objects to their first UV layer" my process of using it is to just select everything, go to edit, switch to face select mode, in materials I select the material that will have the beamng skin applied (usually something like "CARNAME_main"), then it's ready to edit the UV (most of the time) I've never done python before, so if it's a bit screwy, I'm sorry. If you want to take my work and redistribute it in any way, that's okay, as long as you're not profiting.
