This an axe model I made for a video-game.
scale is set for a 1h weapon. The file does not contain the material files shown in the rendered picture. I used substance painter to create maps and render.
There are actaully 4 models in the file due to LODs in game, if you arent planning on using in game you may wish to delete 3 of them.
as for other file formats I do not keep my 3ds liscence year round, only as and when I get work, so its hit and miss if I can send the correct file types for you.
