Should I always keep all edges looping? After finishing Blender Guru's both doughnut and anvil tutorials I conceived that I should keep mesh quad-only. Moreover, all edges of my final meshes were looping, which I took as a rule too. But is there such a rule or how strong this rule is? Sometimes I end up with meshes like on the picture below, where all the faces are quads, but not all edges are looping. How bad is it?



More specifically, should I keep all vertices always connect four other?
The best way to work is having a good topology (here's why why we need topology).
In low poly or other situations you can probably ignore a not perfect topology.

In particolar good looping are super userful if you need to control thge curvature of your mesh.
