I searched for tutorials on how to achieve that effect that I can draw strokes onto live surfaces via API like that:
Also, I looked up to search for examples inside the "devkit" that Maya offers, the hint got was I have to use the class "mpxToolCommand", but to my surprise, those examples which use that class does not work with Maya 2020 because of the viewport 2.0 somehow.
I wish I could show some code but unfortunately, I actually don't know where to begin, does anyone have a little hint to guide me into the right direction?
