Armature gone haywire

This rig seemed to be going so well… then I opened it up and found it gone completely nuts. The culprit seems to be the left hand bone, called HandMain.L. This bone should be connected (and as far as I can tell it is) to the arm bone, but in pose mode, it’s not acting connected. On the contrary, not only is it moving completely independently of the arm bone, but it’s completely screwing up the whole rest of the armature. I’ve looked everywhere I can think of to see how it might be differently set up from the corresponding bone in the right hand, but I can’t see any difference.

Very grateful to anyone who can save me on this one!


Fixed it.

It turned out that there is a 0 length IK chain in the left pinky. That will definitely be something to be on the lookout for in the future. Ouch.

I suppose the reasoning behind having zero length represent the whole chain is simply to save the hassle of keeping track of exact counts of bones in certain chains. And it also seems sensible, I guess, that this would be the default. But it certainly can lead to a screwed up armature if you’re not careful.

Please don’t use that site to upload to again. I got 8 attempts to download addware. Use these, they’re Blender regulars:


Will do. Thanks.

Any other recommended upload sites? Neither of those two have accepted my attempts to upload .blend files.

Strange, I use all the time.


Thanks, Alex_G, that seems to work.

Fligh %, I don’t know what the problem is, I seem to be timing out. It might have to do with my location.
