# Exporting and re-importing
|
||
|
|
|
||
|
|
If you want to use a ProBuilder Mesh in another program, such as a 3D modeling application, you can use the **Export** action to save it to one of the supported formats. For example, you might be using a ProBuilder Mesh as a placeholder while greyboxing, but eventually want to create or enhance a complex Mesh.
|
||
|
|
|
||
|
|
You can also export your ProBuilder Mesh to the Unity `.asset` format and re-import it to use as a Prefab or spawn it in the scene.
|
||
|
|
|
||
|
|
> **Caution:** When you export a ProBuilder Mesh to file, remember that if you want to re-import and use ProBuilder tools and actions on it, you need to [ProBuilderize](Object_ProBuilderize.md) first.
|
||
|
|
|
||
|
|
This section provides information on which formats are available, how to export ProBuilder objects to file, and also some tips for re-importing back into Unity.

## Supported formats
|
||
|
|
|
||
|
|
ProBuilder allows you to export GameObjects to the following formats:
|
||
|
|
|
||
|
|
| **Format:** | **Description:** |
|
||
|
|
| :------------ | :----------------------------------------------------------- |
|
||
|
|
| `OBJ` | Wavefront OBJ. This is a widely supported model format. It supports multiple Textures and Mesh groups. |
|
||
|
|
| `STL` | A widely supported format, generally used in CAD software or 3D printing. It only supports Triangle geometry. |
|
||
|
|
| `PLY` | Stanford PLY. Generally supported and very extensible. It supports quads and vertex colors, but not multiple Materials. |
|
||
|
|
| `Asset` | Unity Asset format, only readable in Unity. |

## Exporting a ProBuilder Mesh
|
||
|
|
|
||
|
|
To export one or more objects to one of the [supported formats](#formats):
|
||
|
|
|
||
|
|
1. Select the object(s) you want to export.
|
||
|
|
|
||
|
|
2. **Alt/Opt+Click** over the **Export** button.
|
||
|
|
|
||
|
|
The [Export Options](Object_Export.md) appear.
|
||
|
|
|
||
|
|
3. Select the [format you want to export to](#export) from the **Export Format** drop-down menu.
|
||
|
|
|
||
|
|
The other Export options change depending on which format you selected.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
4. If you're exporting an OBJ to use in Unity, disable the [Copy Textures](Object_Export.md) option.
|
||
|
|
|
||
|
|
> **Tip:** When you re-import the Mesh, follow the instructions under [Re-importing an exported Mesh](#reimport).
|
||
|
|
|
||
|
|
5. When you are finished setting the Export options, click **Export**.
|
||
|
|
|
||
|
|
6. Use the file browser to save the exported 3D Model.

## Re-importing an exported Mesh
|
||
|
|
|
||
|
|
When you import the OBJ format, select the 3D Model file from the Project view, and on the [Material tab](https://docs.unity3d.com/Manual/FBXImporter-Materials.html) of the **Model Import Settings** window, set the following options:
|
||
|
|
|
||
|
|
- Choose **Use Embedded Materials** from the **Location** drop-down menu.
|
||
|
|
- Inside the **Remapped Materials** section, expand the **On Demand Remap** option group.
|
||
|
|
- Choose **From Model's Material** from the **Naming** drop-down menu.
|
||
|
|
- Choose **Project-Wide** from the **Search** drop-down menu.
