The update of our Industrial package for Unity-3D is ready, version 1.1. We added a lot of new models namely containers, an oiltank, concrete barriers, barrels, new materials and a complete scene and environment for Unity-3D.

Just drag and drop the models to the Unity-Editor and let your scene shine:
