Expedition canisters for water with a volume of 20 and 5 liters. The color of the model can be changed through the Mix map in the material diffusion slot to any colour (red in set by default). Model on a separate layer. Turbosmooth in render only mode on all objects and made a single instance. In obj model without smoothing, it is recommended to apply turbosmooth in at least one iteration. Polycount is specifies without turbosmoothing and for both canisters.

For Corona render, it is recommended to install a version of at least 1.5, since the glossiness of materials is configured taking into account PBR

Have a nice renderings, friends.
