I'm working on using curves to make hair. The curves have a profile bevel which is a shape I've created from another curve. When I move the points around, however, the orientation of that bevel profile rotates around the curve to the inside.

For example, I'm working on a character that has curly hair. The front has a big curly part (like Luca's). When I edit the points to make it curl around, almost in a tunnel, the part of the hair on the outside rotates around to the inside.

I can twist it all back by selecting all the points and using ctrl t to twist them all back, but then there are weird dents or folds in the hair, as seen in the last image. If I could just manipulate the points without the design rotating around the curve, I'd be good.

before moving the hair points

after i twist all the points to 'fix' the problem

Here's what happens when I move the points where they're supposed to be.

  • $\begingroup$ 2 things: experiment with different tilt interpolation in properties/object data/active spline to reduce "dents"; to reduce tilt, make your curve pointing in +x and rotate in object mode to +z instead, and don't adjust the tilt on the first (root) control in the curve. $\endgroup$

  • $\begingroup$ Hi Nathan, Thank you for the suggestions, unfortunately I didn't experience much success with the active spline settings. Additionally, I'm unsure exactly what you mean with the x and z axes, can you explain that part again please? Thank you. $\endgroup$
