Mudbox can import UV
texture coordinates onto a model in the 3D View.
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.
NoteUpdating 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 3D View,
proceed to step 2.
- If two or more models appear in the 3D View,
select the model you want to have the UVs applied by selecting it
in the Object List or using the Object select
tool in the Select/Move 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
Increase a model’s resolution.
- Select File > Import UV...
The file browser appears.
- Select the model file whose UVs you want
to import and click Open. Valid file formats are
.obj, .mud, and .fbx.
An Import
Options window appears.
- Set the Import Options as
follows:
- If the model whose UVs are being imported
is topologically identical to the model in the 3D
View (that is, has not been edited in any way that would
affect the number of vertices or vertex IDs), select the Match
by: Vertex ID option. This is the default setting.
- If the model being imported is identical
to the one in the 3D View, but has been edited
in some way that has resulted in a modification to the vertex IDs
or vertex order, select Match by: Position.
This option attempts to match the UVs based on the world space positions
of the vertices on the model.
