I know I'm probably making some silly mistake after hours of consecutive work.
I have a cylinder representing a gun barrel, and at one point I want to add a 'ring' around the barrel, as shown below.
At the point shown, I added an edge loop, beveled it with hopes of extruding it along the normals, however I'm getting weird behavior.
The faces refuse to extrude outward, and will only go sideways like the second image. Here's my interface too, which I scanned for mismatched settings but can find none.
Can you see what's wrong? I checked for duplicate geometry, found 0 double vertices and I tried doing it with a new primitive cylinder, and it works like a wonder. Thank you!
