So I made this entire crucible building in blender. After a bunch of research and animating this thing three different ways five different times... I finally got it into UE. I landed on, one armature, with 11 bones. 1 for the sliding car, 1 for the vertical motion, one for the crucible. 2 for the front and 2 for the back chains. 2 for a bezle curve for the front chain and 2 for a bezle curve for the back chain. The chains themselves are made with array modifiers which change the length based on the length of the curve, which has its endpoints hooked to two bones. Works fine in blender... but apparently that modifier doesn't count as part of the fbx. So... my question is... how on earth can I clip/shorten these chains as the crucible rises?
