Maya 2020 | Proximity Wrap Deformer
Senior Maya Product Owner Will Telford demonstrates the GPU-accelerated Proximity Wrap deformer introduced in Maya 2020, which binds geometry by proximity without requiring a rest-pose and is topology-independent.
Abstract
This Autodesk demo shows the Proximity Wrap deformer in Maya 2020 driving a character head with a modeled cage, highlighting that it is topology independent and can bind geometry in a non-rest state. The presenter creates the proximity wrap from the deform menu, adds the face mesh as driven geometry and the cage as a driver, then tunes settings such as the bind distance, smoothing of incoming influences, normal smoothing and soft normalization to clean up the deformation. It also demonstrates adding and removing eyebrow geometry from the deformation on the fly and swapping between high and low resolution cages through a choice node in the node editor without rebinding.

- Category
- Production talk / tool demo (Maya 2020 Proximity Wrap deformer)
- Contributions
- Demonstrates the GPU-accelerated, topology-independent Proximity Wrap deformer binding a head mesh to a modeled cage without requiring a rest pose
- Tunes bind distance, influence smoothing, normal smoothing and soft normalization to clean up the deformation
- Adds/removes eyebrow geometry on the fly and swaps high- and low-resolution cages via a choice node without rebinding
- Context
- A practical realization of cage- and proximity-driven deformation, conceptually rooted in pose- and example-driven deformation work such as Lewis et al.'s 'Pose Space Deformation' (2000).Builds on: Pose Space Deformation: A Unified Approach to Shape Interpolation and Skeleton-Driven Deformation
- Correctness
- Vendor demo, not peer-reviewed; the deformer is product-proven and GPU-accelerated, but quality depends on cage placement and the proximity/normalization settings, and non-rest binding assumes the driver cage adequately envelops the driven mesh.
- Clarity
- Accessible and hands-on; one watch conveys the workflow and the key parameters.
- How to read it
- Watch once for the bind-without-rest-pose capability and the parameter roles; revisit the smoothing/normalization and cage-swapping sections when tuning your own proximity-wrap setup.
