Proper gradient tool for easy workflow
For example, I can't texture my character in Substance Painter that way - nor Substance nor Unreal Engine support this! The only option - bake maps inside Blender!
What I mean, is that I just can't do smooth gradients with 4-5 colors, which have different positions, and especially if I want to place gradients precisely around model, or lots of gradients with masks, but with lots of transitions (visible-not visible-visible etc - on ONE mask).
Also, It's not a user-friendly to position gradient based on "Position" map. It often gives me wrong direction of gradient or is generally slow to make gradient I want.
Something done like in 2d app (like Affinity Designer) would be much better option! I mean placing visual gradient scale directly in 3d viewport!
