| Nov 9, 2020 at 18:41 | comment | added | Tim Brennan | I have a feeling that a IK constraint with a pole target might be the answer, but I have yet to find a tutorial that explains it in a way that I can apply to my situation. | |
| Nov 9, 2020 at 17:05 | comment | added | lemon | I think that's possible only under some angle limits for the main bone. If you push the angle above them, constraints will be relaxed. blend-exchange.giantcowfilms.com/b/KM6SVBP2 . May give a try to rigid body constraints, instead. Will give a look when possible but don't know that very well. | |
| Nov 9, 2020 at 16:39 | comment | added | Tim Brennan | Thank you for sending the file. It is much more robust, but I need the two vertical bones to be slightly different lengths so there is a gradual tipping action on the horizontal bone. I am hoping to experiment with different lengths and positions of the vertical bones to see what tipping motion is possible for the horizontal bone. Does that make sense? | |

| Nov 9, 2020 at 15:33 | comment | added | lemon | @TimBrennan, Could you add some pictures describing the cinematic you want? Something where you indicate key positions of the bones, done manually. | |
| Nov 9, 2020 at 15:30 | comment | added | Tim Brennan | There are issues that happen with using the empties as targets. In some positions the rig jumps all over the place. I've been looking for a few hours for a tutorial that covers the fundamentals of mechanism rigging. I've found a few good advanced ones but I still don't fully understand the fundamentals well enough to achieve what I want. Any help would be most appreciated! | |
| Nov 8, 2020 at 18:06 | comment | added | lemon | ok... that seems to confirm I've really misundertood what you wanted... but great if it works as you expect. | |
| Nov 8, 2020 at 18:03 | comment | added | Tim Brennan | I think I might have solved it. I used a "track to" constraint like you said, then I created an empty at the head of bone.002 and parented the empty to bone.002. Then I created a track to constraint for bone.001 with the empty as the target. | |
| Nov 8, 2020 at 17:49 | comment | added | lemon | oh... ok.. you want the head to be attached to the middle of Bone.001 (not its tail)? I've understood the opposite from the first video... | |
| Nov 8, 2020 at 17:15 | comment | added | Tim Brennan | Thanks again. I tried that and it now is fixed which is great but the problem is that bone.002 goes straight through bone.001 and I need it to stay attached... like this youtu.be/myj_1HFFvU4 | |

| Nov 8, 2020 at 16:07 | comment | added | lemon | You can use a track to constraint instead. Same principle | |
| Nov 8, 2020 at 16:02 | comment | added | Tim Brennan | Thanks, lemon. That's very close, but I need bone.002 to be of a fixed length and not stretchy. How would I do that? | |
