RBD Convert Constraints geometry node

Converts existing constraint prims into constraints with different anchor positions.

On this page
Since 18.0

This SOP converts existing constraint geometry to constraint geometry between the same pieces with different anchor positions.

RBD Convert Constraints

The RBD Convert Constraints SOP allows you to easily take your existing constraints and convert them into a different type of constraint. The Constraint Type dropdown menu lets you decide if you want your constraints to be from the Center of Mass, Surface Points, or Faces.

Tip

Use the RBD Exploded View SOP to better visualize how your constraints are connected between the pieces.

Center of Mass

Surface Points

Faces

Parameters

Constraint Group

The primitives in the constraint geometry to convert.

Constraint Type

Center of Mass

Creates constraints between the Center of Mass of 2 pieces.

Surface Points

Creates constraints between neighboring surface points of 2 pieces.

Faces

Creates constraints between connected face centers of 2 pieces.

Surface Boundaries

Pushes the constraint anchor positions to the pieces' surface boundary.

Single Point

Moves both anchor points to a single location along a user defined prim uv location.

Prim UV

When Constraint Type is set to Single Point, select the prim uv on the constraint to move the two anchor points to.

Scale Attributes

Divides the resulting strength and stiffness attributes by the number of newly created constraints between the same 2 pieces.

Max Constraints

The maximum number of constraints between 2 pieces.

Guide Scale

The scale of the guide geometry for visualization.
