| [**Bake Texture Maps**](/asset-transformer-studio/2026.5.0/api/python/algo_functions.md)                                                      | Create textures maps (map types: Diffuse, Normal, Opacity, Roughness, Specular, Metallic, AO, Part ID, Material ID…) out of the selected parts, providing they have normalized UVs.**TIP**: By default, maps are baked with a padding (or "dilation") of a few pixels, defined in the `Padding` parameter. It is also possible to bake maps with an "infinite" padding, in order to avoid issues like [mipmap bleeding](https://docs.unity3d.com/Manual/texture-mipmaps-introduction.html) when seeing a model from a distance. To do so, set the value in the **Padding** parameter to `-1`. |
