This node recomputes the transform attribute by orienting a reference axis to the children joints in the hierarchy. By using an up vector, the orientation will be performed iteratively starting from the root of the hierarchy and will use a lookat method for computing this orientation. The node can also recompute the transform attribute from an existing reference pose given by the second input.
The list of joints to orient.
The list of children to consider. If a joint has more than one child, an average position of all of the children will be used. Adding an entry in this group field will make sure to orient the joint to the added entry rather than any of the other children.
A reference vector that will be aligned to the children joint. A value of 0,0,1 will align the Z axis to the child joint.
A value of 0,1,0 will use the Y axis as the up vector of the joint.
Use Parent to Orient Leaf Joints
When a joint doesn’t have a child, use the parent joint to compute the alignment. This orients the leaf joints.
The skeleton to orient.
Optional reference skeleton to use. The orientation from the Reference Joints will be kept instead of computing an orientation from scratch.
