touch (let alone multi touch) support is terrible ATM. I can see square brush but square brush aren't a thing IRL and they kind of defeat the point of what's good about flat brushes. Usually you don't need art pen to be able to have your flat brush working fine (ie you make a large line, take a 90° angle without rotating to a fine line, then another one, still with barrel rotation untouched, to use the largest bit of the brush again, as seen here) but I've been unable to get that to work in Artrage, even /w my Wacom Art Pen that I read is supposed to be supported.

no flat brush? That's the main 'natural painting' brush. Also not tying Brush size to preset seems a bit crazy. In those mode, aerographe could use up to 3000% (!) size to be useful. Standard pro format for print will be something like A4, 600 dpi. That being said I tried to give it a go on the cintiq and I am a bit puzzled by some 'very much in your face' issues. I am glad to say he's a much happier camper than he's ever been so far on the digital art front. When my 9 yo son was starting to get frustrated with other apps on his Surface 3 (Krita being a bug fest there.) I remembered ArtRage and when I found about the discount, I bought it. I appreciate the brush tech, which seems to do what Painted aimed at but with proficient coding skill (ie it works, performance wise) and a slick UI. I had my sight on Artrage since the first release. The later being my go to setup where I have all my settings adjusted. I have a good experience of Photoshop oc, but also Corel Painter (not suited for real work IMO), SAI, Illuststudio / Clip Studio Paint for the main ones.
