I might not have the lasspath initialized...how do I do that??
I looked under environment variables but there was no Classpath, only the

Should I make a new one called classpath? and which path do I put there?

Thats a little bit more clear and it sounds like a loader problem. As far
as I know 3DS clones existing parts of the scene (like the legs). If the
loader doesn't supports this correctly it may be that only one leg - the
original - appears.

Just a very quick note:
In our experience, changing the field of view is preferable to scaling
the model because if you ever run the code in a VR environment, scaling
produces some undesired results, especially for architectural models :-)

The reason you see this is because of the front clipping plane is
intersecting your geometry. A simple ray is not sufficient enough for
geometry intersections if you want to prevent this sort of situation. A
