![]() Scaling occurs on a plane vertical to the spline tangent. Use these function graphs to define the apportionment of size along the length of the deformed object. For example, if From is set to 0% and To to 100%, the deformed object will be stretched along the entire length of the spline. Use these sliders to define over which stretch of spline the deformations should take place. Values of less than 0% and greater than 100% can also be defined - this can lead to interesting effects, especially when End Mode is set to Extend. Use this slider to move the deformed object along the spline. In most cases, the slider can stay at 100%. Use this slider to adjust the overall strength of the deformation. If you use an oblong-shaped object that would normally run along the length of the spline with its longitudinal axis, the object will point in a direction of the world coordinate system and Axis should be set accordingly. Imagine the axis as a direction in the world coordinate system that runs along the length of the Spline Wrap, passes through the original non-deformed object, and transfers object vertices onto that object. Set Axis to either +X or -X if the pen should be arranged along the length of the spline. ![]() I’ve also tried using the Spline Wrap object but I’m running into similar issues.Īny ideas on how to work around this issue would be greatly appreciated.The pen is pointing in the X-direction of the world coordinate system. Having to manually position each corner point along a rail spline for each Sweep Nurbs is going to be too time consuming to be practical. ![]() I realize the banking of the Sweep Nurbs object can be controlled with a rail spline, but I want to avoid that if at all possible since the animation is very long and contains several of these long, randomly turning ribbons. I’ve seen this sort of thing before using shorter splines and the Sweep Nurbs object, and have always been able to fiddle with the settings to get the correct result, but I have not been able to arrive at a setting this time that prevents these problems. The problem I’m having occurs at certain points along the spline where a 90 degree turn occurs and I either get an awkward twist in the ribbon, or the rectangle is swept along the path such that it creates a tiny thin line instead of maintaining the intended dimensions of the ribbon (see attached image). From there I’m using a Sweep Nurbs object to sweep a thin rectangular spline along the original spline. I’m using a linear spline drawn on a 3d grid as the basis of each ribbon. ![]() These ribbons are made up of straight lines that bank at fairly random 90 degree angles. I’m creating an animation where you follow several 3d “ribbons” as they grow through space. ![]()
