@fredo6 said: You can control the weight of the control point by mousewheeling on the small pin. This changes the curvature for the previous section. Thanks for the reply! I tried this, but it seems to change the "tension" value for the entire segment. I was hoping for controls like this: [image: 3qBJ_AnimationBrokenFree.png] This is from Unity, but most 2d and 3d packages have a similar UI. You can control the magnitude and direction of the tangent on each side of each segment endpoint. For a cubic bezier this corresponds to the "inner" two control points. It's a pretty standard UI .. is there some reason you didn't implement this in FredoSpline? Thanks! Tyler
