photoshop's 3d elements
So, looking at photoshop and programs like Armorpaint and even substance painter I have to ask myself- Everyone has Photoshop, which has allowed hand-painting of 3d models for over a decade, and I'd be surprised if the already great tools from all those years ago didn't improve dramatically, there being no shortage of customers who use them. However- why then get Armorpaint or Substance? What are the heavy drawbacks/limitations of Photoshop that other programs, even ones from Adobe itself, are developed to fill in the gaps? Heck, Substance is WAAAAAAY more expensive than Photoshop and best I can tell it's Photoshop that's less dispensible. But from the folks who LIKE photoshop, hence asking here- what is it lacking on 3d texturing?
