Applying a HDR but do not want it in the background render.

Can anyone tell me is there a way to apply the HDR file but hide it in the render. I have tried putting a panel behind the clock but find it’s affecting the material as you can see. Is there a way to make the plane not appear in the clock material?
Any suggestion would be appreciated.

Cheers, Kordo.


I’m doing this from memory so I’m probably dead wrong, but I think you can set the background in the Render tab from ‘Sky’ to ‘Key’ for a transparent background, save the picture as a png, then slap it over white with nodes or in photoshop.

Thanks BlackBoe,
You must have great memory skills.
I’m very grateful for you help.
