If you assign a mapped material to a parametric object, but forget to turn on Generate Mapping Coordinates, coordinates are automatically turned on by the Renderer at render time. In addition, if you assign a mapped materia with Show Map in Viewport active to an object, that object’s Generate Mapping Coords. option is turned on.
The Show Map in Viewport flag is now saved with individual materials, so you can drag mapped materials from the modeless Browser onto objects in your scene, and the mapping appears in the viewports.
