2nd Camera view as image texture

[flight404]

Is it possible to use the view from camera as a texture I can use in a material? I believe c4d would do it using the mograph camera shader, but from what I have read, this is not (yet) supported in Octane 3.x.

I can get around it by rendering the view from the first camera and then bringing that image back in as an image texture. I was hoping I could do this dynamically so I can constantly reposition the first camera and use that view as a texture.

I looked at the frontalmapping.c4d that aoktar posted but I noticed there should be some Xpresso in the sample but that layer is showing no Xpresso tag. Is this something that can be solved by some Xpresso?

Suggestions? And thanks for your time.
