You can create an IK chain with as many joints as you want.
Notes:
- guides should not be placed in a straight line.
- This node is most predictable with three joints.
- Rotation and twist of the IK system are controlled by the tip ctrl.
Guides:
- '{Number} Guide' - Position where the IK joints will be. Number of guides is determined by the attribute 'Joints'.
Attributes:
- 'Single Side Guide' - For some Aim Guides, the 'side_vector' (twist) is locked and driven by a single 'side_vector', which keeps the orientation consistent. Uncheck this attribute to unlock them if you need more control over the twist. Re-template is required when changes are made. [Video]
- 'Ctrls Scale' - Scale all the node ctrls. Note that the attachments 'Ctrls Settings' and 'CtrlsShape' will override this.
[As of version 1.06.03] 'Update' button to change the ctrls size without requiring a rebuild. [Video] - 'Clean Transformations' - If checked, the zeroed pose will be the same as the bind pose; if unchecked, when zeroing the ctrls, they will align with a world axis specified in the following two attributes. [Video]
- 'World Orientation' - The world axis the ctrls will align with when zeroed. Usually, this attribute's default value is the correct value. [Video]
- 'World Orient Twist' - Along with 'World Orientation', defines the ctrls zeroed pose. Usually, the default value of 0 is the correct value. [Video]
- 'Expose RotateOrder' - Exposes all the ctrls 'RotateOrder' attribute in the Channel Box. [Video]
- 'Secondary Ctrls' - Secondary ctrls are added under some ctrls to help prevent gimbal lock.
A visibility attribute is added to the parent ctrl. [Video] - 'Joints' - The number of joints/guides; modifying this attribute requires a 're-template'.
Connections:
- 'Root Input' - Drives the 'root_ctrl'.
- 'Tip Input' - Drives the 'tip_ctrl'.
- 'Root Output' - An output at '0000_jnt'.
- 'Tip Output' - An output at the tip joint.
