Mid-detail model of a rotating 'gravity wheel' space station from the far future, inspired by the station in the movie 'Elysium.'
Suitable for long/medium shots or as a background element; detail may not hold up in closeups if you are working in 4K for example.
Sub surf modifiers are applied.
The main bulk of the station is one object with the inner 'hatch' split into multiple objects so it can be animated like a lens aperture.
Materials are set up for Blender Cycles with procedural textures providing additional detail/weathering. It is loosely UV mapped purely to allow the procedural panels to apply correctly. With some TLC it could be properly unwrapped & textured but that wasn't necessary for the purpose it was created.
The model was built to scale in Blender so is huge and may need scaling down to be workable in other programs!
