PS: Poor Suzanne once again had to suffer for that demonstration. But don't worry, she will be recreated quickly 😉!
Thanks for linking to this updated feature! Including this addon in the course has taught me to rarely use non-trunk addons in courses. It's too risky to depend on their continued development and it often increases the learning curve for viewers. Having this feature built into Blender is the ideal solution. Only about 6 years late 😅
Better late than never 😂! Blender 2.91 once again is a big leap forward 👍!
