This is a Compressed Gas tank that I made as cargo for a game I'm making. It is 9x2.8x2.6 meters (30x9x8.5 feet), the tank volume would roughly be 37000 liters or 10000 gallons.

It is 1 mesh with 2 sets of PBR textures at 2048x2048.

Unity Standard - albedo, metallic, normal, ao and PBR Metal/Rough - basecolor, metallic, normal, roughness, ao

Each set has three color versions, Orange, Blue and Green that were baked in Substance Painter. All product images were done in Unity.
