Couple of issues.

  1. Could you please explain in a little more detail? Because where do I choose the template? As soon as I press the yellow button and load the UNREALeditor it already starts with a level or scene that is completely black:

  1. So CM would be the preferable unit setting for both softwares ( and unrealed)? I work in with mm. I thought this wouldnt be an issue.

New question:
5. I created some static meshes from a BSP today and I see that all these meshes have 2 material elements.

And after putting a normal material (only color) in both slots I get this (see above screenshot) as a result after building the lighting. Ive forced the overridden lightmap res to (1024) but it doesnt change anything. Any ideas what this might be causing it?

Also is there a way to have 1 material element? By removing the second one or something? no idea how to delete 1 material element.
