Build Assembly Rig

Auto-rigging step of the assembly workflow. Produces Natsura's specific assembly rig that preserves instancing through placement and supports effector-driven posing.

Build Assembly Rig performs the auto-rigging step of the assembly workflow. It takes the imported source geometry (typically a hierarchy of packed instances with pivots at the base of each branch, bud, or leaf) and produces Natsura's specific assembly rig: the structure that lets effectors on the Assembly Decoration apply rigid joint rotations rather than per-vertex deformation, keeping instancing intact through placement.

Inner utility of the Assembly Resource wrapper. Can be placed at the top level for granular step-by-step assembly authoring when the wrapper's defaults aren't the right granularity.

Parameters

ParameterDescription
Name AttributeThe attribute that identifies each assembly instance. All points sharing the same value are rigged as one assembly. Typically matches the Name Attribute set on Import Assembly upstream.
Name PrefixPrefix added to the rig joints' names.
Max RadiusMaximum radius used when generating the rig from the input geometry.

Notes

Auto-rigging fails when:

  • Pivots of input instances are not at the base of branches, buds, or leaves. Fix interactively via Pivot Edit.
  • The input is at an extreme scale mismatch. Fix via the Uniform Scale on Import Assembly.
