Shoulder rigging question

[jdexforwords]

Hi, this is my first post at here. I hope someone who has good experience at the stage of Maya character rigging.

I'm now trying to do my character's shoulder rigging based on the article on Cane-toad.com's briliant tutorial(http://www.cane-toad.com/tuteRig_Shoulder.htm).
Everything going well so far, but finally when I finish the rigging, joints are moving very weird.
When I rotate my controlShoulder joint, It's OK with 2 axis (Y and X). In the case of Z axis, it looks good when I DON'T rotate any other 2 axis at all. But Z rotation doesn't work well with other 2 rotation.
I know that tutorial said it's expected and you can fix it with changing joint's rotation order. I tried all of rotation order, but nothing of them works well.

I attach my MayaAscii file. If you have some time to spare, please look at and make me correct.

Your problem is with your rotation order. In the file you posted three of the joints have different rotation order. Put all of the joints on YXZ and it will work. This is not to say that you will not (and you will) run into problems with gimbal lock. That is the stuff of a whole new discussion. If you want to learn about what gimbal lock is go to ( http://www.anticz.com/anticz.htm ). If you want to learn how to solve gimbal lock go to( http://www.mit.edu/ ) and study, study, study. So far, I have not seen a solution for gimbal lock but there are ways to cheat it. Good luck.

Thank you alan.

Now you make me clear about this problem. I can perfectry controlled original joints.
But as you know, I'm still having trouble with Gimbal lock (flipping over the 90 degree). I think need more extra locator to avoid this. And (Off course) I must go to MIT and learn about Gimbal lock!

Thanks again.

are you using pole vectors? if not then you should... doesent sound like a gimbal prblem is it just flips arount it sounds like a pole problem... Also is your initial pose predictable?
