Houdini 20.5 Nodes Geometry nodes

Joint Capture Proximity geometry node

Supports Joint Deform by assigning capture weights to points based on distance to joints.

Since 19.0

This node assigns capture weights to geometry points based on its distance to joints. A stronger weight is assigned to rest geometry points that are closer to the line between joints in the capture pose (second) input.

This node is typically used for geometry that is not fully closed, and provides a starting point for further painting using the Joint Capture Paint SOP. For closed rest geometry, it is recommended to use the Joint Capture Biharmonic SOP instead.

This operation does not visibly change the geometry (except to possibly add point colors for feedback). To actually change the geometry to the animated pose input, use the Joint Deform SOP.

Parameters

Group

Optional point group on the rest geometry to capture.

Capture Group

Optional point group of joints from the second input to use for capturing.

Weighting Method

Specifies whether joints captured by a point need to be connected in the capture pose skeleton.

Weight From

Weight from either the point location or surface location (for NURBS or Bezier surfaces).

Drop Off

The strength of the capturing. Larger values usually means that more points are captured.

Max. Influences

The maximum number of joints that any point will be captured to.

Blend Factor

When turned on, uses the blend factor to blend the result with the existing capture weights from the Rest Geometry input.

Normalize Weights

When turned on, adjusts the capture weights so they add up to one for every point.

Ignore Skeleton Connectivity

When turned on, ignores the connectivity between joints from the skeleton, treating all the joints as if they are free floating instead of as bones. Note that changing this parameter necessitates changing Drop Off as well.
