Extraction
Certain 3D modeling tools can attach UV mapping information to the surfaces. When importing models, Patchwork 3D attempts to conserve this information, which remains attached to the surfaces. This is the case, for example, for the importation of Autodesk 3DS Max models.
Extract mapping operator allows you to apply, depending on the selected UV set, the unfolding made in the unfolding workshop. Cf. Unfolding & Stitch Workshop
