In a curve SOP, I created a "Polygon Curve" and I turned the "Reinterpret Curves as Current Type and Order" on. Now, when I change the primitive type option to the "Bezier Curve", it changes the shape of the curve which is not what I need. I want it keep the shape while it convert the curve to the Bezier one. How can I fix it?
It’s not possible to preserve the shape. An order 4 (degree 3) bézier curve will interpolate smoothly between the control points. If you want a linear bézier curve try setting the order to 2 (degree 1)
you can append Convert SOP, set to Bezier Curve and check Interpolate Through Hulls, then if you want you can append another Curve SOP and continue editing as bezier
