ArmorPaint (aka Armor Paint or Armour Paint) is an open-source standalone for painting on 3D models, including with PBR. Very like Substance Painter, but free and with no subscription shackle. Or… sort-of-free. It’s 16 Euros on GumRoad, where your $20 also gets you the latest builds dropped into your GumRoad Library. Or you can compile an .EXE yourself for free from the source-code — if you have a few hours to spare, a copy of Microsoft Visual Studio (free, when last heard of) and a YouTube tutorial handy.
ArmorPaint has had a couple of big updates, and the latest is now 0.8 (19th January 2021). There was another big update you may have missed hearing about, this time last year. There’s a YouTube video for ArmorPaint: Four key new features, January 2021…
“Added Viewport cel-shader plugin”.
Nice. It’s ‘two-clicks’ instant too, and it appears there’s no need to fiddle about with setting up special toon materials. No lineart on the edges, though you might paint along the seams. For the huge list of fixes and changes, including new .SVG import, see the Changelog.
There’s a Blender bridge, but as yet not ones for Poser or DAZ.
Apparently the freeware Materialize, from Bounding Box Software, is said to work well with ArmorPaint as a flanking ‘assistant’ software. Materialize can “create an entire material from a single image”…
