Exporting Refraction, reflection, indirect lighting


I spent my last to days figuring out how to export a shot from UE4 frame by frame and save all sorts of passes, around 20 per frame. Even though nearly everything that the compositing doesn’t need is there, passes for refraction, reflection and indirect lighting are missing. They are hightly needed in film making.
And the lighting parse looks somewhat odd.

Is there a function in UE4 I’ve been missing to output these passes or is it simply not possible (yet)?

Would love to get some help, thanks a lot!

I found a variable called “Indirect Irradiance” over the pixel inspector, it might be the right variable, but is there a way to create a map from it?
