I have just finished this scene, it took me 4 months to finish and it's based on the x-mansion from x-men movies.
I used 3ds max, substance designer, painter and unreal
all materials were created in designer then used painter for baking and texturing
it's my first scene in ue4 and I learned a lot from it..
