When you zoom in on a vignette, you receive one of the following error messages:

• "Please try again..." 
• 403 Forbidden error message
• S7 Alert: Object of vignette is too large

Solution

Do one of the following:

• Reauthor the vignette to make the objects smaller.
• Call it at a smaller size (try different values of res= command).
• Try setting the material on the objects themselves, rather than at the top level of the object hierarchy.
