Hi,

Im trying to get stuck into rigging with Mocca and not doing bad so far. Ive watched tutorials and now building a human rig. Im having problems with my hip controller "home" position set up with "user data" and xpresso. After moving it around a bit, when I hit my user data button the hip controller doesnt go back to where it should. It is something to do with it's rotation value. Ive played around with this for a while now and cant see what ive done wrong. Please can one of you righteous riggers take a look and give me some pointers please?

File is here (http://www.pixelwork.com/CGTalk/HumanRigv1.zip)

P.s. Also if you notice anything else that is wrong with the rig so far, please let me know, Im a noob to this and wanna learn!

Because the hip controller is a handle in the spline IK it needs to keep its rotation.

Put another controller in the same position as the hip controller, then make the hip controller a child of that controller. Then move your expresso to that new controller and add a userdata to it.

Rig is looking good so far. :)

Well, what I did was take out the FK Spine Controller, made the Body Comtroller 90º on P (which made the Chest and Hip Controllers zeroed out, and it seems to work.

Then maybe you can redo the FK Spine Controller. That seemed to be messing up things aas you rotated the Body Controller earlier, too.

Cool, those worked, that's great!

Thank you! I shall can carry on now and rapidly approaching the daunting stage of figuring out animation!

If anyone else downloads the file and sees anything wrong or things that could be improved, please let me know.

Howdy,

Also for your Home button Xpresso you can set the second input on the Condition node for the Rotation to 0,1.57,0. Since Xpresso works with radians instead of degrees, 1.57 radians = 90 degrees. ;)

Adios,
Cactus Dan

Cool, great tip there, never knew that! So many different ways of doing the same thing!

Thanks Dan, oh and by the way ive seen your tools in action and they look like they make life alot easier and quicker to set up! So maybe one day I will invest in your pro toolset! It depends on the individual, but I think in my case learning the long way round first, I then learn a bit more, gain more of an in depth understanding....then look for the easiest and quickest route!

theres also a degrees to radians and radians to degrees converter node if your more comfortable working with degrees.
