Mudbox can import UV texture coordinates onto a model in the . Supported file formats include: .obj, .mud, and .fbx.
Importing UV texture coordinates onto an existing model is useful when:
- The model you are sculpting in Mudbox has no UV texture coordinates. That is, its possible to sculpt a model without UVs.
UVs are required when you want to perform any texture extraction or paint work.
- The model being sculpted currently has existing UV texture coordinates that require an update for any number of reasons. Since
Mudbox has no feature to edit UVs, this must be done in another 3D application. As a result, sculpting and texturing work
can occur concurrently in separate applications and the UVs updated on the model later in the production pipeline.
Note
Updating the UVs on a model within Mudbox that has pre-existing textures could result in the textures not appearing as expected,
depending on the changes that occurred between the old and new UV coordinate layout. It is recommended that paint/texture
work be performed only when the UVs are final.
- UVs can be imported to only one model at a time. Do either of the following:
- If one model is in the , proceed to step 2.
- If two or more models appear in the , select the model you want to have the UVs applied by selecting it in the or using the select tool in the tools tray.
NoteUVs can only be imported onto the base subdivision level of a model (Level 0). Use the Page Down key to return the model to
the base subdivision level. For more information, see

- Select .
The file browser appears.
- Select the model file whose UVs you want to import and click .
An window appears.
- Set the as follows:
- If the model whose UVs are being imported is topologically identical to the model in the (that is, has not been edited in any way that would affect the number of vertices or vertex IDs), select the option. This is the default setting.
- If the model being imported is identical to the one in the , but has been edited in some way that has resulted in a modification to the vertex IDs or vertex order, select . This option attempts to match the UVs based on the world space positions of the vertices on the model.
