This section we’ll setup the curve controls for the rig. We follow the arm but the same would be for other parts too.
Simple Biped Skeleton With Controls
This page walks through building a simple Maya rig using big buck bunny from the Blender Foundation as our model. We’ll be manually building each part so we know exactly how it works and is based on the manual rigging course.
Creating Curve Controls on Big Buck Bunny’s Arms
This is the contraint method of setting up curve controls on a skinned fk big buck bunny skeleton.
Building An IK rigHelper setup on Big Buck
So since we have controls to think about building the ik leg setup in a rigHelper group gets a little tricky. These videos take us through the process.
Building Controls – Dual Leg Skeleton Setup
The important difference for the curve controls is that we’re making them for Ik. So we need the following controls
1. foot control
2. ball control
3. hip control
4. leg pole vector
5. optional toe controls (if you have toe joints)
This section we’ll prepare and setup the ik/fk switching.
The Dual Leg Setup Building the 2nd Skeleton
CLinking The Dual Leg Setup To The Curve Controls
This section we’ll show how to setups the hips and move all control, this is a very simple setup for the hips and an fk spine.
Creating the Hip Controls
Creating A Move All Control
Now we’ll setup the head with an aim.
Orienting The Head With An Aim Constraint
Many riggers forget about rotation orders, but these are very important for animation. If we’re thoughful about out rotation orders it can help the animators down the line.
Check Rotation Orders on World Controls
By default all objects in Maya are set to XYZ gimbal rotation order, but many controllers are better setup in other orders such as ZXY. In particular pay attention to the feet and hips.
Here’s the manual way to colour controls.
– Colouring Curve Controls
1. Attribute Editor
2. Attribute Spread sheet
Little trick for parenting things like the geo inside the rig and not having double transformations if we move the root group.
The Inherits Transform Checkbox for Double Transforms
Setting the selection sets to make it easier to key the rig for animators.
Adding Selection Sets
Selection sets make is easier for the animator to easily select multiple objects easily in groups. Sets are usually
1. For fingers
2. for all body controls
3. later we’ll put all facial
4. Later we’ll put all controls
Riggers might also want to create a set for all of our bind joints, the ones we use to skin.
