Just to add my opinion, I believe orange peel is a byproduct of paint JUST drying.
Here's why: I used to be big into model car building, and among the other builders I spoke with, all had a routine for smoothing down their finishes after the paint dried, since most paints (lacquers, acrylics, enamels) have solvents in them that evaporate while the paint is drying, leaving behind an inconsistent surface.
I would think it would be difficult to INTENTIONALLY make orange peel (factory or handspray) unless you used a paint that had a very FAST evaporating solvent or you thinned it down and painted with such light coats that the paint never actually had a chance to sort of "blob together and smooth out on an area".
When I'd paint those model cars, I used either Duplicolor lacquers or offbrand Enamels. More often than not, I had resulting orange peel when I used the Duplicolor lacquers that dried within a few hours versus the Enamels that had an oil-based solvent that would literally take 2 months to fully cure. If I had a lucky day with the right temperature and humidity, I could lay down a coat of enamel paint and have it come out close to perfect, but of course I couldn't actually work on the paint until it cured. Whenever I would spray with lacquers, I would feel like I put down a really nice coat because when the paint was wet, it was evenly laid and glossy, but when the paint cured the next day I'd find it to be eggshell-y or orangepeel-y.
It would seem that the VOC regulations that require automakers to use paints with less environmentally-harmful solvents would be akin to me painting with lacquers (although I believe the VOCs from when I painted with lacquers were much worse than when I painted with enamels). The solvent evaporates away from the paint much quicker, giving the paint less time to mix and mingle into a smooth finish.
