It’s not possible to render several camera perspectives from UE4. If you think about it, imagine the performance impact that would have….Also, Multi-machine means a separate workstation per camera perspective, so in that case you will get the output from each capture card in a vision mixer and set up the Multiview there.

I have been asking Aximmetry for a long time for a feature where the output from each slave workstation is sent back to the master workstation over NDI. Hopefully it will be available soon.

Thanks for your reply TwentyStudios!

I got more questions on kinda the same topic. 

Here's how work flow is set-up now:
2 slave PCs with professional DE with 1 camera connected to each as a part of multimachine setup.

1 master PC with broadcast DE with unreal scene loaded and both rendered cameras received from other 2 workstations.

They are set-up as in the FAQ for multi-machine set-up. (Remotes with IPs in cameras, shared folder for project, etc.)

This picture of multiview comes from the master workstation. If I directly check what is on my capture cards pins from 2 slave PCs - I get just rendered image of my camera. Is this right? Or should I receive something different?

Also when I loaded aximmetry pre-made studios (like sports or talk show) I get normal multiview as it should look like.

So my questions are:
1. Is this multiview possible only with studios made in aximmetry not unreal?

2. Is my setup right or am I doing it wrong?

I don’t follow exactly… With the Multi-machine setup you can get a preview of the cameras going into the slave workstations on the master workstation, but they are only intended for preview. You should use the final composite from the video card on each slave workstation in the actual production. 

As I said, UE4 can only output a single camera angle per workstation, so the multi view won’t render any background. This only works with the Aximmetry 3D engine.
