Is there any functionality that allows extending and shrinking bezier arm? At default, they are in fixed lenght and it is only possible to move them around, not to change their lenght- it goes both to Animation window and Shuriken curves editor.
No, it’s not possible since the tangents are stored as a single value which just describes the angle of the tangent. Take a look at the Keyframe struct. It just has two floats, one for inTangent and one outTangent. As far as i remember the example in the decs is wrong. They don’t store the angle in degrees but the tangent of the angle.
