Replacing player camera with a fullscreen texture

I’m looking to implement a fairly complex effect which involves rendering multiple cameras then compositing them into a texture to show as the main viewport. Is there any straightforward way to disable the default player camera and simply show a textured quad instead?

The idea of the player viewport being a camera seems fairly ingraned in the engine but I’m hoping I missed something.


Did you ever get this working or perhaps a viable workaround?

Could you not just render the texture as a UI element on the camera with UMG?
