Well, I couldn’t paint in Blender if someone put a gun to my head - I would need to use 3D Coat or Substance Painter or something else I’m familiar with (I used Blender STRICTLY for input/output to other things).
But if you are suggesting it brings it in and preserves those UVs so I could then export as FBX and paint elsewhere… that would be helpful. However - I’d still have to bring it back and unless that plugin supports such things (as importing an FBX to export in something Flight Sim can use) I’m still back to where I started (which is I will NEVER be able to paint my own livery).
