Dear John,
Thank you! I'm still having troubles, and yes, I have not used Rayshade
before. (I don't even know how to view it after saving it in winxp).
I didn't see an option regarding "transparent" when using Rayshade
though.

I'm trying to make a protein folding landscape in my ppt slide,
and then put several protein configurations distibuted at the various
location at the landscapes. However, because of the "frame" of the protein
structure, my landscape looks kinda bad by overlaying with boxes.
The goal is to use animation mode provided by the ppt and show these
figures one at a time on the landscape, as if they are "rolling" down from
the top of the landscape to the native state.

Thank you, please help....

I have photoshop element installed... but I havent used it before
(pls forgive my ignorance in windows).
