Perforated Corrugated sheet metal. Vray Render

I’m looking to make Perforated Corrugated sheet metal. (Not the same as the last topic) Vray Render. I need to be able to see though the material once rendered in Vray. Is there a way to render so that is has a transparent background and saved as so as a PNG. Thank you for your help. Mo.

I did a video on how to use alpha channels. This might help you, so check it out.

Here is a video from 2021 about using PBR and perforations in Rhino 7 (the previous post has a 404)
