thnx
Hello,
You can do this with a post processing effect:

Isn’t there a way to access the functionality already in the editor? I mean it’s there and I really don’t feel like getting into this whole postprocessing stuff on top of everything else I am learning
Welcome to UE4, where difficult things are easy and easy things are sometimes incredible hard. 
To make this less a pain, here’s a good YouTube video explaining all the steps:
… and here’s a ready-to-use project (the post-processing material necessary for this is just insane): Multi-color Outline Post Process - Tom Looman

Thanks. After my comment I searched the marketplace and I actually found two projects for sale there that not only do outline but also paint the object in a different color and allow an object to shine through a solid object in front of it.
Since I don’t feel like getting too much into all this material and postprocessing stuff, i will buy one as soon as I figure out which one is better for me
