Unwrap UV

Automatically generate clean UV layouts, preparing models for manual texturing or AI Texturing — good UV means no seams, no stretching.

TL;DR

  • Automatically generates UV unwrap layouts, preparing models for manual texturing or AI Texturing.

  • UV quality directly impacts texture results — good UV = no seams, no stretching.

  • Recommended to run after Remesh and before AI Texturing.

When to Use

  • UV was lost after Remesh and needs to be regenerated.

  • An imported external model has no UV.

  • AI Texturing results show visible seams — better UV layout is needed.

When NOT to Use

  • Your model already has high-quality UV (carefully crafted in a DCC tool).

  • You don't need textures (e.g., STL export for 3D printing only needs geometry).

Step-by-Step

  1. Select the target model.

  2. Enter the Unwrap UV tool.

  3. The system automatically calculates the optimal UV layout.

  4. Preview the UV island arrangement and check for excessive stretching.

  5. Confirm and save — you can now proceed to AI Texturing.

FAQ

What does Unwrap UV do?
It automatically generates a clean UV layout, unwrapping your 3D surface into 2D space so textures apply without seams or stretching.
When should I use Unwrap UV?
Use it after Remesh, when an imported model has no UVs, or when AI Texturing shows visible seams.
Do I need to Unwrap UV before AI Texturing?
It's recommended — good UVs are the foundation for high-quality, seam-free textures.
Does Remesh remove my model's UVs?
Yes. Remesh rebuilds topology, so you should regenerate UVs with Unwrap UV afterward.
When can I skip UV unwrapping?
Skip it if your model already has high-quality UVs, or if you only need geometry (e.g., STL for 3D printing).
