Automatically Unwrap UVs for the UDIM Workflow with InstaMAT's nPass Graph

In this video, we build a reusable node that iterates through every material section in a mesh, unwraps UVs, and lays everything out into UDIM tiles automatically.

:sparkles: Featured:

  • :repeat_button: nPass iteration to process each material section by index

  • :brain: Self-termination so the graph stops when the work is finished

  • :safety_pin: Buffer + append to accumulate a final combined output mesh

  • :compass: UDIM tile transforms to prevent overlapping UV shells

  • :abacus: Row/column grid layout using modulo + division for cleaner UDIM layouts

If you’re building procedural workflows and want a hands-off way to unwrap and tile UVs, this one’s for you.
