Painter once was my main art tool but I hardly use it now. Completion went far ahead in almost every aspect. Still it has a hidden treasure : a depth channel for impasto effects. True 32 bit one.
I am a texture artist working for games and years ago Painter was everything I need. Not anymore. I use Substance , Mari and other soft and hate them all. All them lacking that surface touch and material feeling Painter always provided . Sometimes I open Painter to feel for a moment that old "at home" nostalgia then have to go away. It's absolutely useless for me in its current state.
But all this could be changed with just a few minor additions:
1. Depth blending method of very simple math combining layers based on its depth. Like one in Quixel mixer. basically (Max of layerA and B) - layerA for blending mask
2. Ability to export depth as 16 or 32 bit grayscale image/layer . Somebody did Blender addon for that but I can't even find it anymore
3 . Few live effects/adjustments like turning depth into normal map and hipass+ levels to make cavity maps
4. maybe something like "patch tool" and "inpaint" from Affinity Photo working on both RGBA and Depth in sync
Those features would open a whole new market niche for Painter since I am not alone who hates all that robotic Substance approach Adobe following and I would gladly buy updates every years
Good ideas and useful for 3D texture work too. Export of impasto data layer, for use in Photoshop for image finishing work, would be handy!!!
