Houdini 20.5 Character KineFX

mappedconstraints

Constrains two TransformObject nodes based on a matching mapping property.

Since 20.5
This feature is still under development. The current functionality is unfinished and subject to change, and may have thin or no documentation. Please bear this in mind when using it.

This component constrains two TransformObject nodes if they contain a matching mapping property. When a fktransform component converts a skeleton joint hierarchy to a TransformObject node hierarchy, it adds a mapping entry to the properties dictionary attribute on each node. This mapping entry contains the name of the reference skeleton and the joint that was used to create the node, for example, "mapping:Guides.skel":"hand_l".

Note

Currently, this node does not handle offsets. It assumes that the joints have the same xform values.

Parameters

from

The TransformObject node to contrain to the node in to. This parameter accepts APEX path patterns, so you can specify tags in this field, for example, %tag(fk).

to

The TransformObject node that the from node is contrained to. This parameter accepts APEX path patterns, so you can specify tags in this field.

mapping

The mapping to find in the properties dictionary of the from and to TransformObject nodes. This parameter is in the format mapping:<skeleton>, for example, mapping:Base.skel.
