This Is a simple rig cable only made with joints, IK, curves and controls. Low triangle count used for animated work instructions. It also has only 150 joints. The asset had to be created like this so when it is animated, baked and saved to a Unity project it works correctly. Unity only accepts animated joints and pivot points.
Right now on the internet all you see is character rigs by the millions but no other assets as much.
A cable and wire can get very complicated to rig at times. I know there will be highly skilled riggers that will say cables and wires are easy to rig. I can tell you from a beginners point of view its not. To me a character is a lot easier to rig to me. I have created over 40 of these so for and each was completing different setup. I will post more soon.
