Parallel (or setable) palette knife angle
Just started using AR2 on the advice of some other Blender artists I know. I'm one of the (minor) Blender developers, but an artist, too. One thing that I really miss from real painting is angling the palette knife. I know from working as a dev that something like making the knife angle run parallel to the motion of the brush instead of perpendicular to it is probably next to trivial, but it would add a lot flexibility to the tool. Beyond that, a setable angle would be great for things like rocky cliff faces, etc.
I know you guys won't be opening sourcing this tool ($20 is more than fair), but oh how I would looove to get my fingers inside that code!
Great tool! Keep it up.
