Setting up the leg


Reverse foot lock


Mirror Joints


Spine and Parenting legs

(Youku videos below)


My Maya model file can be downloaded here

Select the model Modify > Freeze Transformations

02_freezeTransformation

This will convert your body values back to 0 and 1. This will be very handy when you start animating.
03_freezeTransformationsChannels

(This step is not important, but it helps me with orientation)

Create some text saying "left" and "right" on your model.
04_createText

select your text and body and create a new layer from them.
05_selectTextAndBody

The button in the top right hand corner in the image below will create a new layer with the selected objects. I called my layer "body_model"
07_NewLayer

Joints

Now for the joint tool. Its in the animation shelf, or skeleton > Joint Tool
08_jointTool
The joint tool is the middle tool in this image

Work in the side view. Select the joint tool and start from the hip. Make a second joint at the knee, then ankle, ball and toe. Put a slight bend in at the knee.
09_leg_Joints

rename these joints. r_jointname_JT (r for right, jt for joint). This is important when you mirror your joints later, and when your rig becomes more complicated.

Reverse foot lock

Start at the heel, then go toe > ball > ankle. Name the joints r_rfl_jointname_JT (rfl for reverse foot lock)
10_RFL

Mirror Joints

Move the rig over to the right side leg.

Skeleton > Mirror Joints > Options

12_mirrorJoint

Mirror joints along Y axis.

Search for "r_" and replace with "l_"
13_mirrorJointReplace

Do this with the reverse foot lock as well. When moving the RFL, press and hold "V" while moving to snap into place.

Spine

Start at the bottom and follow the back up to the neck. On my model I had six joints, but it depends on the model.
14_spine

Name the bottom (first) joint "root", then pelvis, back1, back2, back2 and neck.

Parent legs to spine

Select the hip first, then select the pelvis (not the root).
15_parent_hip
The spine should be an aqua colour, and the leg white.

Edit > Parent. Do this for both legs.
16_edit_Parent

Your legs will now be joined to the pelvis joint
17_rootJoint

Finally, select the rig (from the root joint) and create a new layer with it. I called mine "rig"
18_rig_Layer

That's the first step! next is to orient joints and set up IK handles.
