I downloaded Blender the other day and did the chess piece video tutorial. It was my first proper completed model so I’m quite pleased with the result. One thing I had a problem with though. When I used shift-e to change the angle between 2 sections, I noticed later that this caused what can only be described as stretch marks. They were lines extruding from the surface (spherical) and they seemed to be perfectly spaced. When I took the curve back to normal they were gone.
Is this just something that happens or is there a way of preventing this?
