UAZ Hunter in an expedition modification in bright orange color. Moderate contamination, cannot be turned off, because baked into the texture. There are mid detailed interior and engine. The stack is collapsed
everywhere except for the smoothed parts and tires with the FFD modifier (left uncollapsed in case fully inflated tires are needed). Model on a separate layer. Turbosmooth in render only mode on some objects, but made as a single instance. The OBJ model has no smoothing. Used Corona Legacy materials, including Corona Triplanar maps.
For Corona render, it is recommended to install version no lower than 1.5, since the glossiness of the materials is adjusted taking into account PBR.

To fill the trunk, I recommend the following models:

Have a nice rendering, friends.
