I was recently inspired by the latest Star Wars movie (I liked it :-)) and created a laser tower from The Empire Strikes Back movie.
The model is intended for any game engine with a Metal/Roughness PBR material capability. It was created using Blender 3D and textured with a combination of Substance Designer, Inkscape and Mari. The model has 9796 verts and 12164 tris as reported by Unity3D.
Well the mount holding the dish looks almost new and almost plastic-like. Below that the clean pivoting base suddenly gets corroded. Likewise, the matrix-like panels on the dish look new, whereas the dish itself is grungy. To me it just seems a little inconsistent. But it could be written off as repaired components.
