Is UV Split Node

The Is UV Split node outputs a selection indicating which edges in a mesh are UV splits. A UV split occurs when an edge connects two faces that use different UV coordinates along that edge, causing a discontinuity in the UV map.

This node is useful for detecting UV seams, isolating edges used for UV islands, or creating procedural operations that depend on UV boundaries.

Inputs

UV Map

The UV map to evaluate for discontinuities. This input must be a vector attribute representing the mesh’s UV coordinates.

Outputs

Is UV Split

A selection identifying edges where the UV coordinates differ between connected faces. True for UV seams or discontinuities; false otherwise.
