Rendering the Image Plane in the Maya Viewport

[Doodle_Monkey]

Hello,

I've read in some of the documentation that you should be able to render the Image Plane of the Viewport in Maya. This would really help me render my models on actual photos so that I can more quickly match lighting and perspective. The documentation states that I would need to enable "Alpha Channel" and disable "Keep Environment". It doesn't give any indication about what alpha channel or where. The same for the Keep Environment setting. I can't for the life of me, find the Keep Environment setting. Can you assist me?

This settings are in the kernel node.
