Houdini 20.0 Nodes Geometry nodes

Labs UDIM Tile Number 1.0 geometry node

Creates a UDIM tile number attribute on primitives, points, or vertices.

This node compares an input UV attribute with the standard UDIM grid to derive the corresponding UDIM tile number for each vertex or point. It then promotes the UDIM tile number to an attribute on primitives, points, or vertices.

Parameters

UV Attribute

The vertex or point UV attribute from which to derive the UDIM tile number.

UDIM Tile Attribute

The UDIM tile number attribute to create. This attribute is first created on the class of the UV attribute. It is then promoted to the target class using the most common value. For UV islands outside of the UDIM grid space, the corresponding UDIM tile number is -1.

UDIM Tile Attribute Class

The class of the UDIM tile number attribute.

Visualize UDIM Tile Numbers

Visualizes the UDIM tile numbers from the lowest to the highest on a color spectrum. For UV islands outside of the UDIM grid space, the corresponding visualization color is grey.
