[Closed] Maxscript, backburner rendering render elements

I have made a script that takes files from directory, and sends them to backburner for network rendering. When I run the script it renders fine but without the render elements they dont show in the backburner monitor nor do they save. If I open some of the files manualy and send them to render with backburner it works fine, but not with the script? The render element is VrayAlpha, but I dont think it matters.

EDIT:
The thing is I want to save only the alpha channel from the render, is there any way without the render elements?
