How to export refraction, reflection and indirect lighting maps

The past 2 days I spent learning how to use UE4 for rendering and got surprisingly far. I got to the point of being able to output around 20 passes per frame. Some are useless, some not important but still some are missing.
Refraction, reflection and indirect lighting to be specific. And I need them badly for compositing.

Does anybody know and feel like telling me where to find and how to export these?

Thanks a lot!

Unlike common composition workflows, you only have these to choose from.

This is due to the nature of real-time shading and lighting in UE4.
