I’ve been working on this collection of knobs for a while. I thought it would be simple. But like most things…simple is rare. I ran into difficulties controlling fillets in meshes that were sub-surface ready. The model would look good until the sub-surface modifier was added. You can get some strange looking artifacts if you don’t have good topology.
