Then, if an animator tries to move the bone, it will not allow the movement. Turn this lock on for bones that you do not wish to move during animation. If you try to move it, it will not move, but try to move its neighbors if Manipulation Affects Neighbors In Hierarchy is on. When on, the position of this bone is locked in Animation mode. If you want to add a feature to the rig, then the setup controller is the place to do it. If you put a modification into a layer, it should apply strictly to that scene, rather than to the general rig setup. The layer system is designed to hold keyframe controllers when you want to build a complex controller configuration, it is often better to put it in the setup controller so that it is embedded in the rig, not restricted to a particular layer. The layer system does not get saved with the rig preset, so if you were to save a rig preset, you would lose your work.
Why not just put these procedural controllers into a layer, and then apply an additive layer on top for the hand keyframe touches? This would give you procedural motion, but with the benefit of CAT's layering system overlaid so you could easily add touches of hand animation on top of the procedural animation.
If you’re setting up a face rig, you could also write a script to generate automatic eye blinks, or slightly inherit rotations from the eyeball movement. If you set the utilitys Pick Layer option to Use Setup Controller, then the CATBone chain is constrained to an IK chain using the Setup mode layer. In fact, the Apply Max IK utility on the Animation menu Animation - CAT submenu does exactly this. You can constrain the tail of your character to a spline, or an IK chain to use spline IK on a tail. This would give you flexible control over the way your limbs behave instead of simply ineriting rotation from the ribcage. You could then create a new object, applying an Orientation constraint that targets the ribcage and pelvis, and use this object to drive the setup orientation of your limbs. For example, you could make the hands face downward, but apply a LookAt constraint to the setup Rotation track, assigning an object high in the air as the LookAt target, and the ribcage as the Upnode. You can simply assign a constraint to the setup mode controller to define the base value for the animation controllers to animate from. You might want to use this capability to customize the inheritance of the arms or head of your character. You can apply your own procedural animation controller setup to the setup controller, and then make the layer system relative to that controller. The reason you might want an animation controller in setup mode is to take advantage of the feature Additive to Setup Pose. Track View hierarchy of CATbone with Setup Mode set to: When you choose the Animation Controller option, you get a Setup animation controller, as a child of the LayerTrans (Layer Transform) track, that you can view and edit in Track View.
The idea of the setup pose is that it cannot be animated, so no setup animation controller is available by default. Animation Controller Alternatively, you can set a bone to use an animation controller to define the character pose in Setup mode.īy default, CATBones use a static transform value called SetupTM, which is not visible in the animation editor (because it can't be animated), and is accessible only via MAXScript.Static Matrix Value By default, Setup mode is completely static, and the pose that the character returns to in Setup mode is defined by this matrix.Static Matrix Value / Animation ControllerĬhoose either of the following to determine the character pose in Setup mode (when returning from Animation mode): When off, moving the bone moves its children. When on, moving this bone in Setup mode causes it to stretch. If you try to scale it, it will not resize. When on, the size of this bone is locked in Setup mode. If you try to rotate it, it will not rotate. When on, the rotation of this bone is locked in Setup mode. When on, the position of this bone is locked in Setup mode.
