This is an environment I made in blender using 2 main gun metal color trimsheet materials that are duplicated to red, yellow and white. And 1 material for the decals. If you turn on the visibility of the wireframes you'll be able to see and noticed that it's relatively low-poly and that most of the details are from the trimsheets.
The lighting is a lot better in blender because I'm only allowed 3 lights here in sketchfab.
