VR 3d painting

Hey guys,

i would like to add the ability to paint in 3d with motion controlers in my virtual reality game (like a very basic tiltbrush). But i didn’t really find any information or hint on how this could be possibly done. Does anyone have an idea or starting point what to use? Do i have to spawn new meshes for the paint or is there a better solution? Help would be greatly aprreciated!

Edit:
Sorry now i found this post here:
