first of all I accidentally stumbled upon this program on some forum, before this I worked with AutoCad and 3ds max, and I must say that MoI is one of the most intuitive programs I ever used, after I installed it took me only about 10 minutes to figure how most of the stuff works.
now here is one of my first models I made with MoI, Orkan (hurricane) MLRS which I'm probably gonna use in some mod for CnC3
finished model in MoI
rendered with 3d max, only thing I had to do is to adjust the polygon smoothing groups after importing the model to max and make some small tweaks to the model
