Bake the AO to add Grunge Trying to follow along with tutorial I've done everything EXACTLY as he decribes every step of the way --however at only 35 seconds in when I try to "Bake the AO" I get an error message "No active UV layer found in the Object Suzanne" --what didn't I do right?

How to Grunge
A UV map is required in order to bake.

To UV unwrap a mesh, switch to edit mode (&#8633; Tab) and press U.
Usually an automated method like Smart project or Lightmap pack is good enough for baking, but for other uses you may want to use manually placed seams.
