Better controls of lights casting shadow and glass color?

Hello experts,

I am trying to get the result as below in Stager:

2 aspects I don't know how to achieve in Stager:

Firstly, as you can see, the light is casting the purple color of the glass bottle on the ground. I've tried to play with the glass material but can not get this result, Kindly any hints on how to achieve this?

Secondly, I found that when we set up multiple lights for a better lighting result for the bottle, it is no way to control which light can cast the shadow. What's more, all lights are brightening certain areas of the ground surface (no matter whether it is the "group" in Stager or it is an object), and it is an unwanted "side effect" to the final result. Are there any ways in Stager that enable us to control surfaces receiving lights or not as we do in MAYA? Or are there any specific methods we can use in Stager?

Looking forward to suggestions...

Thanks a lot in advance!
