Storm published first pictures of the IS-3 tank in HD. For some reason, the IS-3 is possibly the most requested HD tank on RU forums, that’s why it’s sort of “big news” for them. It still has no textures, it’s just the first model version.
The vehicle model was made using special method called “photogrammetry”, where the vehicle is photographed from all sides and then, using special software, these photographs are assembled and turned into a 3D model. These photos were taken in the Stalin line museum in Belarus, there are several IS-3 tanks in various state of disrepair.
