Unreal to marmoset?

As part of my course we must make a short animation film to showcase. The project leader wants to render out the the film in marmoset. As I’m going to be in charge of environments for the film I was looking into the idea of utilising unreal to create the landscapes and environments however this leaves me with the problem of importing it to marmoset. Unreal would be the best tool with it’s well designed ui and tools (including speed tree plugins). Is it possible to export the scene from unreal to then use in marmoset?
