This is the high poly model of the mg3a1 I made as part of the leopard 2 mbt I'm working on.
NOTE: since this is only a reletaively small part for a much larger model (a tank), I didn't spend too much time on getting the size and scale 100% percise. In hindsight I think the barrel is a little too long, but I think it will be barely noticeable after baking to lowpoly and put onto the tank model.
I will be coming back to this and put the low poly with texture in here later, possibly much later.
