Script for Rhino and Keyshot(V-Ray)

Hi, guys. I need your help.

I have experience rendering a Jewelry model with a rhino and a K-shot. and i have a problem.

I have to do various stone renderings about one Jewelry model. It’s very annoying.

so, i want making python script.

Are the processes I’ve mentioned possible only by script, without running the rhino program?
*without running means i’m not control rhino program.

If that is possible, what should I study?
Do you have any tutorials to refer to?

did you know the snapshot feature in v6?
is it what you’re looking for?
