Well i've been playing with the ring extrude method you mentioned but i've noticed it doesn't give good topology.

This will be smoothed to form highpoly geo and also then used for lowpoly geo.

The problem is, the edges seem to be slanted.



how can i generate an extrusion along a path where the edges come out at the right angle?

I've also noticed this with extrude when extruding faces that go round an edge
