I get this result. I get the reflections but i dont want to render the rest of the glass(the black plain) I want the rest of the glass to be fully transparent, so when i edit into my scene it would not be anything else than the model and the reflection that is seen.

I want the end result to be only the model and the reflection of it in the glass to be rendered as a image sequence.
But i dont know if that is possible or if there is an easy way to do it?
