I'm trying to create a wallet case in blender, I want to add a system that allows me to comfortably "adjust" one slider to open, close and flip it. Currently I divided the case into two movable parts, the 1st one, that bends, uses simple deform. However I can't figure out a way, to have the 2nd one "connect" to it so that it moves with the middle section, but doesn't bend. At the moment when I slide the angle slider in simple deform I only move the middle section. For now, the 2nd part compensates by using simple keyframes but that's a very inaccurate and slow method. So I'd like to know, is there any way to connect the two, and have simple deform or any other system perform all the work?
