Models that contain NURBS data can be re-tessellated directly in the scene without having to import the model all over again.
Re-Tessellate allows you to fine tune tessellation quality of entire models or individual parts in your scene. Increasing the tessellation value will yield smoother surfaces on your model and increase scene file size. In order to Re-Tessellate, you must enable the Import NURBS Datacheckbox at import (Geometrysection in the Import dialog).
How to Re-Tessellate:
Right-click on a model, part, or multi-selection of parts in the scene tree or real-time view.
This will open the Tessellation Settings dialog. Change the Tessellation Quality or drill down to access finer adjustments including Angle Tolerance, Distance Tolerance, and Maximum Edge Length. For more information about settings, click here.
Click the Tessellate button to show a preview in the Tessellation Settings dialog, which can be displayed as a Wireframe or Glossy representation.
Click Apply and Done to commit the changes to the scene. Cancel will revert all changes and exit the dialog.
