Vermillion is the best app in this space I think. I get to paint with oil paints, and have nothing to clean up and no major expenses like buying more paint.
And with a browser in place, I can watch painting tutorials while actually painting, and not worry that I dont own a specific brush or other tool.
It's awesome. It's on Steam for anything that supports SteamVR or PCVR, and on the Quest store for Meta devices.
