Green texture after Blender 3D (Euro Truck Simulator 2)

When working with blender was faced with such a problem, why after exporting the trailer in the game it becomes green. Tried to export several types of trailers, but the result is the same green texture when connect this mod in the game.
Maybe someone faced with similar?
Most interesting is that in blender the color is not distorted and no greenery, no!
What could be the problem, the mats or script of some kind needed?
Most importantly, the game log is totally clean and does not produce any errors!
