In-Camera VFx basically means using nDisplay to render from Unreal to a wall of LED panels. You get the benefit of live compositing your actors on the virtual background, with light and reflections already applied from the screens instead of having to add them in post.
It’s the workflow you see shown in this project spotlight:
We’re working on documenting the whole process of setting up a stage, but it involves a lot of considerations that aren’t just about how to use the engine (like for example the best ratios between the pitch of the LED screens and the distance of the camera). Look for a white paper on the subject coming out soon.

Hi ! Do you have an example project for us to toy with in the meantime ?
I’m having difficulties to see how to setup things in the editor in the first place.
Intuitively there should be some reprojection of the camera view on the LED wall but I’m struggling to see how to do that in ue4 at the moment.
An example project could give us a grasp of all the things involved engine-side.
Thanks in advance,
