Paddle Steamer engine

ENSONIQ5:
Cheers Johnar.  I came close to walking away from this many times, it's satisfying to see it running.  Hopefully I can "finish" it (if any project is ever truly finished)!

nemyax:
IK would make this setup a piece of cake.

ENSONIQ5:
Hmm, maybe, at least in some places.  Most IK setups I've seen are strictly hierarchical in the sense that 'tree-like' structures can be created, but not closed loops.  Child objects can influence parent objects through the IK chain, but you can't have looping chains or multi-anchored chains which this rig would require, as far as I know.  What would make it simpler would be a physics engine that incorporated collision detection, then simply rotating the crank would generate the required motion in the linkages etc.  I've done this sort of thing before in packages that included physics (Cararra) but I kinda wanted the challenge of doing this entirely in Anim8or and rigging it so the animation could be easily changed without re-keyframing everything, which means scripts.
