About the Vignette Update Tool
The Vignette Update tool prepares vignettes for deployment to the Image Rendering system.
It is available from the Start menu on your desktop, in the same program group as Image Authoring.
The Vignette Update tool regenerates Reflection and Alpha maps for the vignettes it processes. These maps overwrite any Reflection or Alpha maps you created in Image Authoring.
You run the Vignette Update tool from your desktop.
