Load UDIMs for Object

See here for more info

Create Single UDIM

This will create a Single UDIM for the currently selected Polygons on your object.

UDIM Per UV Island

This will map each separate UV Island on the objects UV Tag to its own new Material.

Each material will be assigned a selection tag containing all the polygon for that udim.

All the UVs for that UDIM will be mapped to the appropriate UDIM space. For instance any polygons on UDIM 1001 will be from 0 to 1. But any UDIMS on 1002 will be from 1 to 2.

UDIM Per Polygon

This is a bonus feature and should be used with great care.

This will create a new Material for EVERY polygon on your object. It will also create a new textures at the resolution specified in the UVPaint Preferences and assign it to the color channel for this object.

Each of the Polygons UVs will be mapped to the UV space for the UDIM. IE polygon 1 will be 0-1 on udim 1001, polygon 2 will be 1-2 on udim 1002, polygon 3 will be 2-3 on udim 1003 etc...

A new Selection tag will be created that assigns the each polygon to its given material.
