In all seriousness they're nice simple props with no wasted geometry. Every tri is helping to define the shape and the smoothing looks great on them. Great props. :)
unfortunately i wont be around, but i think you should definately speak poop. if for no other reason then it'll look good on a resume, or to protential investors.
The rotating part of the minigun, ie the barrels look bolted to the side of the vehicle Apart from that I like the design, doesnt look speedy, but definately cool!
MoP: Yeah, thats what I said. The lines simply define the parameters of pre-created complex geometric primatives. Neat, but...sorta pointless at this stage.
with the 2020 release, one could add polypaint with the "A" toggle ON (brush settings, next to the RGB settings), to define the areas affected by a layer - and then creating a mask from the polypaint.
