Mwah.... usually it's all external my good friend..My perception is that repainters don't care much for poking around in VC's... Take that very nice looking Pilot's Boeing 314 Clipper, one of the biggest initial debacles in the history of MSFS (:)). The external model looks very nice indeed, well worth an equally nice looking VC. Unfortunately that didn't happen. IMHO an awful green color as one of the reasons. While i don't do repaints anymore this Clipper VC was the reason i had a look into the ins and outs of MSFS repainting (more or less..) with result of a new overall VC color, actually quite easily done (i guess the real deal starts with PBR materials and texture baking). But that's not all of it of course, it's just a good start.
I mean, if i myself, MSFS repaint experience...
