Create a Proximity Pin

The proximity Pin node lets you attach locators directly to a deforming mesh.

Use Proximity Pin when you want to use a transform (instead of UV coordinates, like UVpin,) to be a live connection to your geometry or when clean UV's are unavailable .

To create a proximityPin node

1. Select your geometry.
2. Next, select a locator.
3. Select Constrain > Proximity Pin in the Animation (F4) or Rigging (F3) menu sets.
   A Proximity Pin locator attaches to your geometry at the closest point on the surface from the selected transform.

   

   Proximity Pin: new locator created and transformed afterward

4. When you transform or deform your geometry, the transform moves with it.

Note: The Proximity Pin constraint lets you choose a World space for evaluation, in case no double deformations/transformations are occurring. See Proximity Pin options
