@metin@mbt3d@miekeroth Very nice work, Mieke. I never used Zbrush but have a subscription for quadremesher. I can't live without it. It's a huge time saver and fulfills all needs if you read the docs and know how to use it in complex situations. Face groups aren't really needed. By the way: you can mark faces with some dummy materials. It works the same, and you get independent retopo areas.
