BACK ALL FK RIG

Here is how to do a controller to control the rotations of multiple controllers on an FK Spine.

First draw at least 3 joints from the root of your character (assuming a humanoid). Label the joints Spine_1, Spine_2, and Spine_3; make sure that you use a script such as cometJointOrient.mel from comet cartoons:
http://www.comet-cartoons.com/melscript.php

X axis should be pointed down the heirarchy and the Z rotation axis should match on these joints. See figure:

create 3 NURBS controllers for these joints (I use circles); then create 3 nulls by going to create>empty group or by hitting Cntrl +G with no objects selected.

you will then select Spine_1 joint and then a null and go to contrain>parent (make sure that maintain offset us UNCHECKED in the options). Repeat this for each null and then delete these constraints by selecting them in Window>hypergraph:hierarchy .

move the NURBS controllers to the joint they will control (hold V to snap to a joint); now freeze transformations on your NURBS controllers then parent them P by selecting the controller and then the null associated with the joint they will control. select the NURBS controller and then freeze transformations on them again.

Select a controller and hit control-G to make a group between it and its null. Repeate for each controller and name them BACK_A_GRP, BACK_B_GRP, and BACK_C_GRP.

Select each Spine controller then the joint it controls and do a constraint>Parent Constraint for each one.

Awesome; now you will create or choose a NURBS shape to work as your BACK_ALL_CNTRL. I usually take a larger circle or other shape from a library of controllers I have. Create a null; select the Spine_2 joint and then the null and do contrain>Parent Constraint. Delete the constraint. Now freeze trasnformations on BACK_ALL_CNTRL and then parent (hotkey is P, NOT the same as parent Constraint). to the null. Freeze transformations on the controller again.

Now select BACK_ALL_CNTRL and BACK_A_GRP , BACK_B_GRP, and BACK_C_GRP and go to  window>Rendering Editors> Hypershade.

Now you will hit the graph input and output connections and in the work area selec the little output arrow from BACK_ALL_CNTRL and select rotate> and then connect the green connector to the input arrow of the BACK_A_GRP and choose rotate. Repeate this between the BACK_ALL_CNTRL and each back group.

You are now done; if all is right in the world you now can control your spine controllers individually or all at once with the SPINE_ALL_CNTRL. Well done!

Reverse Foot Rig, Part 2

It's been a while since I have updated....so forgive the absence. I have been one busy gal. If you have found the tutorial helpful or it needs some clarifying on any step, just let me know!

The rest of the reverse foot rig is pretty easy stuff. You have done all the hard work up til this point. Give yourself a pat on the back. Go ahead! You deserve it!

Okay, now back to work.... you can't go patting yourself on the back all day.

As you remember last time we had a heirarchy now set up for the reverse foot. I will usually just go ahead and grab that in the hypergraph and parent it to the rig_ALL_CNTRL ; this is the controller that should be at the top of your heirarchy of controllers.

Once you do that we are going to create TWO groups in this hierarchy. This will be to control the banking of our foot from side to side.

repeat this for the other foot!

Now we are going to do some set driven keys to automate a few of these processes. Stand by in part three!
