Thank you for your quick response,
I would like to have your advice.
I’m doing a video mapping project and need to take out each in-game camera to each projector.
I found this for rendering two windows : GitHub - chaosgrid/ExtraCamWindow: A simple Unreal Engine 4 plugin that allows to have extra game windows with their own camera viewpoints.
I’ve tried it, it has some glitches but I can see how it’s done.
There is also this tread that explains how to chose the default monitor : https://www.reddit.com/r/unrealengine/comments/3j7bo4/is_it_possible_to_choose_the_default_screen_in_a/
It may be a best solution but I was wondering if you have access to in-game cameras in the engine class…
Other solution would be using split screen and extend (easiest method).
I’m wandering if it wouldn’t be a best solution to use an external video-mapping software because the screen is not flat so I would need to do some wrapping, one camera renders the 3D scene that is put onto the uv of the wrapped plane to fit with the screen (I would have to do a tool like this : Projection Mapping Tutorial - Resolume Arena 4 - YouTube). This plane is rendered by two other cameras that represent each real projector.
In this case I would have to find a way to send unreal game output to the mapping software, I guess it’s possible.
What would be your advice ?
