that's an awsome helmet man! looks great! I'm starting on my second pep helm using robogenesis's files, hope all goes well for me, I screwed up the first time by using just normal paper, however, my folds were descent but warping set in on one side of it after I finished, not a horrible one, but never the less un-doable with that type of paper.
EDIT: mind if I ask what pep file you used for that and the scale? I've wasted a ton of paper so far, cant seem to get my scale right, I've read the tutorial on here already for it, math is easy enough, but still not coming out right for me with the pep file im using. My first one that I made was one of flysquirel's pep files, Im horrible at scaling however it turned out perfect!, My pc took a crap and died and I lost the pep file tho. (cant seem to find on here or the armor wiki)
