How to warp for a 3D sphere projection

Hi,

We chooses UE4 for a full motion flight simulator project that uses a half dome with 3D projector.
What is the way to generate the warped 3D pictures for this setup?

I think one kan define a camera to produce the texture for some material and define a mesh to do the warping.
but is this the preferred way? Is it efficient enough? Is there a better way by coding something directly into C++?

And how can we do this for a 3D projector? We need to define two cameras and we will have two separated meshes for warping.
How can we do the 3D rendering in this case?

I hope someone can point me into the right direction.
