| [**Resize UV To Texture Size**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md#resizeuvstotexturesize) | Resizes the UVs existing on a mesh, so they can be used to display a texture with a specific size in "real world" (scanned textures have a real-world size, expressed in real-size units, not pixels). Give a texture target size (in millimeters), and UVs are automatically resized.This is particularly useful when UVs have been automatically generated (see [Continuous UVs from CAD Models](/asset-transformer-studio/2026.5.0/manual/data-preparation-fundamentals/about-uvs/continuous-uvs-from-cad-models.md)). |                   |
