Decal View (UV Editor)

To invoke the Decal View right click the decal (control click on the Mac) in the Project Workspace Tree and select [EDIT]. The Decal View can also be invoked from right clicking (control click on Mac) on a Stamp object in the Project Workspace Tree.
Decal view UV Editor
If the decal is selected in the Project Workspace Tree then all control points can be edited. If you select just a Stamp in the Project Workspace Tree then only the control points that were effected by that particular decals application (Stamp) can be edited.
The Decal view displays the patches of the model in the way they are covered by the decal. This allows fine control over how the decal is actually stamped onto the patches. Moving the geometry in the decal view actually is changing the position of the decal. You can have a modeling view and a decal view up at the same time and watch the results to your model in real time as you are adjusting the patches in the decal view.
Many new features were added to the Decal view editor in Version 11. These features consist of grouping, translate, scale, rotate, magnet mode, and you can hold the Ctrl key down before you select a point to split patches.
