This SOP adds the required attributes to the Rest Geometry input for the Pose-Space Edit SOP . It should only be done once.
Shape Diff Method
Transforms the example geometry into the rest-pose by applying inverse skinning method to the example geometry before computing the difference.
Computes the difference of specified attribute on the two geometries.
Produces a similar result as the Pre-Deform method however instead of transforming the example geometry with inverse skinning this method transforms each point by the inverse of the orientation indicated by a quaternion point attribute.
The name of the quaternion point attribute to use with the Post-Deform Orient difference method.
Use Bone Deform
Skeleton Root Path
Specifies the parent OBJ for the bones attached to the input geometry. The
pCaptSkelRoot detail attribute is used by default when this parameter is empty. If this parameter is non-empty, it overrides the
pCaptSkelRoot detail attribute in the input geometry. Relative path values here will be with respect to this node.
Bone Deform Method
The skinning method used to inverse transform the deformed geometry when using Pre-Deform differencing or Use_Bone_Deform is enabled. The skinning method should match that used by the upstream Bone Deform SOP that deforms the geometry.
The name of the point attribute to use with the Blend Dual Quaternion and Linear skinning method.
