I am currently in the process of building some Eclipse armor out of foam, and let me say, it is pretty easy to work with. All it requires is extensive measurement, and a little trial and error with getting the right proportions. Not to mention, you can get a couple pieces of the armor done each...
Those pep files are really awesome, though I do have one request, does anyone know where I can find an Eclipse Mercenary Helmet Pep? I have the Mass Effect Helmet, and now all I need to complete it is the face plate for the Eclipse Mercenary Troopers. Any help would be appreciated, thanks.
