# RenderUVAtlas - ComfyUI Built-in Node Documentation

> Renders a mesh's UV layout as an image.

Renders a mesh's UV layout as an image. Each connected UV region (chart) is filled with a distinct color, and chart boundary edges are outlined in black on a dark gray background.

## Inputs

| Parameter    | Description                                                                                                                                                             | Data Type | Required | Range                |
| ------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | -------- | -------------------- |
| `mesh`       | The 3D mesh whose UV layout will be rendered. The mesh must have UV coordinates; otherwise the node raises the error "mesh has no UVs to render. Run UnwrapMesh first." | MESH      | Yes      | -                    |
| `resolution` | The width and height, in pixels, of the rendered square image (default: 1024).                                                                                          | INT       | Yes      | 64 to 4096 (step 64) |

Note: If the mesh contains a batch dimension (3D UV or face arrays), only the first item in the batch is rendered.

## Outputs

| Output Name | Description                                                                                                                              | Data Type |
| ----------- | ---------------------------------------------------------------------------------------------------------------------------------------- | --------- |
| `image`     | The rendered UV atlas image, returned as a single-image batch. Each UV chart is colored, and chart boundary edges are outlined in black. | IMAGE     |
