I’m having an issue trying to realise an animation for a four pieces of cardboard, I have set up each piece of cardboard so that when my spiral spline is pulled to the top of the screen the cardboard unrolls, however, what I want to do is have the cardboard bulge out in the centre of its animation and then straighten up near the end into the final shape before I begin the next stage of the animation, I’ve tried rigging the cardboard but it doesn’t play well with the spline, I’ve tried to make the spline controlling the cardboard follow another spline but due to the way I understand the modifiers I can't get it to work either, any help would be appreciated. Thanks in advance. initial direction

secondery direction red, blue wanted directionblue wanted direction into purple finished pose

  • $\begingroup$ I created a uncurling animation and added additional Curve Modifiers to add little curls to the corners. Can you try creating another Curve to match your requirement. You can have as many Curve Modifiers as you need. youtube.com/watch?v=Q6FS9sRJcDQ $\endgroup$ – rob Nov 30 '18 at 11:55
  • $\begingroup$ ill give it a try, however, when I tried this the first time it warped the mesh badly and placed it miles away from the curve even when changing the xyz offsets in the properties panel if the curve modifier. ill get back to you. $\endgroup$ – yhmfzr1000 Nov 30 '18 at 12:27
  • $\begingroup$ Yep, had the same issue originally! Make sure you Apply any transforms, rotations or scalings via Ctrl+A $\endgroup$ – rob Nov 30 '18 at 13:00

Rob was correct just needed to add more work to the splines and make sure everything was applied, transforms, rotation and scaling using Ctrl+A then apply new curve deforms and set the correct deformation axis

fixed curve modifiers
