Sadly, the model used for the original specimen 3 has been removed from the Gmod workshop. (Yes, I use Garry’s mod for all my renders) The original model I used was DarkKnightPL’s Nightmare endoskeleton (http://steamcommunity.com/sharedfiles/filedetails/?id=613310281&searchtext=nightmare+endoskeleton) and since there isn’t any other separate Nightmare Endoskeleton model, and I don’t know how to ports models from the sfm workshop and I don’t know how to use Source Filmmaker, I’m from now on using The endoskeletons inside Failz’s Nightmare animatronics (http://steamcommunity.com/sharedfiles/filedetails/?id=736693118), and since these models weren’t made to showcase the endoskeleton, some parts of the new specimen 3 will probably look very weird. Idk, Expect more news about the remade Proto-Endo soon!
