Houdini 21.0 Nodes Geometry nodes

Character Unpack geometry node

Extracts the rest geometry, skeleton, and animation from a packed geometry primitive.

Since 18.5

This SOP unpacks a character that has been packed into a single geometry with the Character Pack SOP. It outputs the following:

Note

This node differs from the APEX Unpack Character SOP, which unpacks a character or scene from a character folder structure and outputs its skin, capture pose, and animated pose.

Inputs

Packed Geometry

The packed geometry primitive(s) to unpack.

Outputs

Rest Geometry

The character’s rest geometry.

Typically, this will contain polygons with the boneCapture point capture attribute, which can be deformed using the Joint Deform SOP.

Capture Pose

The character’s capture pose.

Each joint in the skeleton is represented by a point, where the P and transform (matrix3) attributes contain the joint’s transform. The point’s name attribute contains the joint’s name, and is matched up with the capture paths in the rest geometry’s boneCapture attribute when deforming the skin. The skeleton’s hierarchy is represented by two-point polygons between the points for each child joint and its parent.

Animated Pose

The character’s animated pose, which is represented in the same manner as the Capture Pose.
