Hello,
thanks for posting this!
Using Photoshop I have created many extremely useful scripts (glass on a mirror with reflection, create only a selection (any shape) and photoshop did the rest) but also some just for "fun"...(create a selection and photoshop made a real looking stone...with moss and shadows/lights, etc...structure, etc.)
I'm confident I can do this for you.
FYI: I'm located in Rochester, NY
thanks again
Martin
