circle control script

Circle control script

This script creates a series of circle controls and circle control groups for every joint selected.

Notes:

1. All joints MUST be named with a "JT_" prefix, as we have been doing in class.
2. Joints must be selected starting in a parent-child descending order; in other words, select the top-most parent joint first, then the next child joint, then the next child joint, etc
3. The selection set for the spinal column would in the following order:
1. JT_spine_lumbar
2. JT_spine_thoracic
3. JT_neck
4. JT_head
4. The script will create a control for each joint, and connect the rotation channels of the joint to the control. The control is then grouped by itself. If it is controlling a joint that is the child of another joint in the current selection, it will parent the control's group to the controller of the parent. 

How to use:

Copy the script below the dashed line into the Python tab of your script editor. Select the joints you want to add controls to, making sure to select the joints in a parent-child descending order. In the script editor, choose command > execute.

-------------------------------------------------------------------------------------------------------------------

import maya.cmds as cmds

sl = cmds.ls(sl=1)

count = 0

lastS = None

for s in sl:

    ctrlName = s.replace("JT_", "CTL_")

    ctrl = cmds.circle( nr=(1, 0, 0), r=1, n=ctrlName)[0]

    offset = cmds.group(ctrl, n="GRP_" + ctrl )

    cmds.parentConstraint(s, offset, mo=0)

    cmds.delete(cmds.parentConstraint(s, offset))

    cmds.parentConstraint(ctrl, s, mo=0)

    if count > 0 :

        cmds.parent( offset, lastS )

    count = count + 1

    global lastS

    lastS = ctrl

Naming conventions

Naming conventions

NOTE: I will be referencing your rigs into an animation file to check your deformations and control structure. 

YOU MUST ADHERE TO THE NAMING CONVENTIONS USED IN CLASS OR YOUR RIGS WILL BREAK WHEN I REFERENCE THEM!!!!

NNOI (Node type, name, orientation, iteration)

Nodetype: describes the category of the node (Polysurface, joint, control, etc)

• CTL – controller - if something is a controller in the rig, it is always prefixed with this.
• PS – polySurface
• NC – nurbs curve
• NS – nurbs surface
• PS – polySurface
• LOC – locator
• JT – joint
• IK – ik handle

Name: describes the functionality or location of the node (arm, head, ikFkSwitch)

JT_spine_1 : first spine joint

JT_leg_R : right leg joint

Orientation: describes which side of the body the node is on

Iteration: describes numbered node iterations

Excellent reference site for articulation and deformations. If you're wondering how a certain area of a mesh should deform, this is a great place to go...
