Hi everyone! (Long-time lurker, first-time poster here)
I'm a bit stumped with a rigging problem (in Maya) that I have, and was looking for some direction/help from the wonderful minds out there.
The setup I'm looking to create is something like this...
All the coloured members are of fixed length; the bottom point is constrained to a single position (like a ball joint), the top point will be free moving (it will move up/down and left/right along the plane that I've drawn, and its movement in/out of the plane would cause the whole plane to move with it...hopefully that makes sense?); and the other joints are all hinges with axes that will always remain perpendicular to the plane.
I've tried a number of solutions using combinations of a couple IK systems, but I always seem to end up with a circular reference...which sort of makes sense (in my mind) because both of the centre pieces (blue and green) affect each other's movement.
Even though I haven't found a working solution yet, the aim is to find a solution that can be easily reproducible with code, as I have a few of these setups that vary slightly, and will vary with newer versions.
Has anyone rigged something like this before, or have any ideas for a setup I should try?
Thanks in advance!
