Using Dynamic Paint To Instance Objects

Hey everyone, hope all is going well for you!

I’ve been trying to follow a tutorial that concerns making polygon/game hair, but the issue is they’re working within Maya. So when they come to the point where they start painting duplicates of an object onto the mesh, I’m completely lost. I’ve been looking into this for a bit and found the information surprisingly lacking. The best I can find is someone watching the same video with someone else responding with the general setup.
They don’t go into how to actually do the painting and duplicating and all that fun stuff, so I’m left clueless once again.

All I know is that Blender has something called Dynamic Paint, and apparently this Dynamic Paint thing can do what I want to do.
How? No idea, so if anyone can point me in the right direction, I would greatly appreciate it.

Thanks, and take care!
