Got a thigh and a shin done, just need to do the strapping on those pieces, but here's me trying them on to see what it'll all look like together, roughly. (Knee pieces aren't done, but just held them in pic to give better idea)
The most frustrating part about the knee pads for was that they weren't technically attached to anything if you've observed in the game (cuz i have no time on my hands, jk ). But this, THIS looks like its coming out awesome! I can't wait to see the finished product!
It's out of paper, resin, interfacing material, and bondo.
It's a method called pepakura. You make a 3D image of what you want with a program, break it down into a 2D scale, scale it to your body size, print it, cut out the pieces, glue all the pieces back together according to the numbers, resin, fiberglass the inside (in this case I use interfacing material instead, cheaper, just as strong), bondo the outside to smooth it, sand it, then paint it.
