Take this example

Upon download, it just give you a .obj and a jpeg for texture so it looks pretty straight forward.
As soon as I import the .obj, here's what I get:

As you see this is zoomed out all the way and the tiny frame in the center is actually the normal field of view. Indeed most times I try importing the simplest .obj, it gives a weird shape stretched to almost infinity. Scaling it down does do much as it ends up just as distorted. I hope this rings a bell to anyone and i'll be able to get some help.
thanks
