Modeled in Blender, Textured in Substance Painter and then rendered in Cycles.

I have kept the topology low enough for video games, with 2K textures.

Extra attention has been placed in realistic rust and dirty areas, as well as scratches, paint blisters and dulled paint.
Many finer details are also hand painted.

Completely quad geometry, including top and bottom grid fill caps to avoid any nasty rendering artifacts from multi-poles.

Textures and object materials has easy to understand and obvious names to make reapplying the textures easy.

All Textures are PBR game ready, Exported in Algorithmic PBR Metallic Roughness.
