Houdini 19.0 Nodes VOP nodes

Parent Constraint VOP node

Constrains a KineFX point’s parent to a new world transform.

On this page
Since 18.5

Shifts the parent to a new transform, maintaining a given constant offset between them.

Parameters

Update Offset

Pressing this button will stash the current values found on the parent and newparent inputs. These stashed values will be used for the parentbind and newparentbind transforms respectively if no nodes are connected to the corresponding inputs.

Clear Offset

Pressing this button will clear any currently stashed transforms, returning the parentbind and newparentbind transforms to identity.

Blend

The weight of the blend between the original transform and the new constrained one.

Components

A mask specifying which parts of the constrained transform to apply to the input transform.

Inputs

xform

The target point’s world transform.

parent

The parent’s world transform.

parentbind

The bind pose of the current parent.

newparent

The new transform you want to constrain the old one to.

newparentbind

The bind pose of the new transform you want to constrain the old one to.

blend

The weight of the blend between the original transform and the new constrained one.

components

The components of the constrained transform to blend.

Outputs

outxform

The updated transform of the given point.

outparent

The parent’s updated transform.
