Render a view of another camera as texture on an object

[ILS]

Is there any way to render a view from another camera as a texture on an object in the same pass.
I know I can render a camera view and use the rendered frames as bitmaps but is there a way to do it in one pass?
Example would be a camera looking at a monitor of a cctv footage of another space in the same model.

I doubt there's a way to do this in one pass.

As I thought I remembered, there's this post discussing this from a few years ago https://forums.chaos.com/forum/chaos...he-game-portal

This includes a link to another post with Vlado's opinion that it's on a potential 'to-do' list

EDIT: And a link to the C4D method https://www.youtube.com/watch?v=pNGnB4cldJc&t=33s

Ray Portal BSDF was recently implemented in Blender and became a hot topic.
V-Ray implementation of Ray Portal BSDF is expected.

I added a request to the official ideas site.

Thanks,
I figured it can't be done now but seeing is it can be done in most game engines feels like it should be doable in vray as well.

+1 from my side too. Some crazy stuff can be done using this tech!
