I loaded up Procreate to take a look at something this evening, and a little "what's new" message was waiting for me. I clicked it and, among other things, Procreate has a 3D mode now. Sweet!
Definitely still a 1.0 addition, but I can't wait to add some more painterly effects to my models without having to do a big export/import dance across my computer and iPad Pro. This software is really amazing.
