Francesco Piacenti, also known as FR3NKD, shared his first tutorial this summer on using displacement maps with Blender and Ucupaint, the free texturing add-on by ucupumar. He has now launched a full Ucupaint course in early access, with new episodes being released regularly.

Francesco's latest teaser for the upcoming lesson appears to focus on bump mapping, but that's only a small part of what Ucupaint can do. Take a look below to see how it can transform your texturing process:
