Stormraven Gunship scene

One of my projects made using 3ds max and UE4 for my individual portfolio piece for one of my 3rd and final year projects at University. Gunship high poly was made last year, the scene, and textures and bakes were all done with a time limit of a week, so there are a few errors. Some models are just low poly with no highpoly bake and a pbr material.
