So it appears that in Blender 4.1 the auto smooth angle that you mention in the video has been replaced with the “shade smooth by angle”. Using this option I was able to achive the same effect that you demonstrated in the coruse.
My question is where do I find the angle selection for this option? I looked where it was in the video and the normals line in the “object data properties” tab has been removed.
Thanks for your assistance.
