Transfer vertex attributes
 
 
 

To transfer UV, color per vertex (CPV), and vertex position information between meshes that have differing topologies (that is, the number, arrangement, and connectivity of vertices on each mesh is not identical) use the Transfer Attributes feature.

Transfer Attributes transfers vertex data by sampling the vertex information on the source mesh and then transferring the information to the specified target mesh, based on a comparison that is spatially based. The target mesh gets modified as a result.

Transferring vertex attributes using Transfer Attributes is useful in the following situations:

While the source and target meshes can vary widely in their topology, the default transfer settings require that the objects be positioned in identical locations spatially because of the nature of the sampling and transfer process that occurs.

You can also use Transfer Attributes to flip the orientation of the UV shells as they appear in the UV Texture Editor. This streamlines your UV layout and texturing workflow.

To transfer attributes between separate meshes

  1. In the scene view, move the source and target meshes so they are positioned and oriented as you want for the attribute transfer. Ensure that the source mesh and then the target mesh are selected in that order.
    NoteThe order of selection is important. The last object selected is always considered the target for the transfer operation.

    You must select the source mesh in object mode, you can select the target mesh either in object mode or by selecting the individual vertices in the region to be modified on the target mesh.

    If you have difficulty selecting either the source or target meshes in the scene view, change the display of the meshes to wireframe mode or select them using the Outliner ( Window > Outliner).

  2. Select Mesh > Transfer Attributes > . In the options window, specify what attributes you want to transfer by setting the Attributes to Transfer options as follows:
  3. Specify how you want the sampling to occur by setting the Sample space setting as follows:
  4. Set the remaining options based on other specific requirements:
  5. Click Transfer to transfer the attributes and close the options window or click Apply to transfer the attributes and keep the window.

To mirror vertex attributes on the same surface mesh

  1. In the scene view, select the components on the surface mesh (that is, faces, vertices, or edges) that you want to have modified by the Transfer Attribute feature.

    The Transfer Attributes feature samples the surface about the specified mirroring axis and assigns new values to the selected components. All unselected components retain their original attribute values.

  2. Select Mesh > Transfer Attributes > .
  3. Depending on your workflow, set the Transfer Attributes options as follows:
  4. Click Transfer to transfer the attributes and close the options window, or click Apply to transfer the attributes and keep the window.
