Weird Error with model

I made some rocks in 3dsmax with baked textures.

I tried to import them into source but some odd errors occured. For me in source sdk and ingame the model was pitch black, could only be seen in mat_fullbright 1

For somebody I sent it to the model didn’t show at all.

Would some kind soul be so kind as to have a gander and either fix the models or tell me how to remedy my issue?

from first read it sounds like a broken illumposition but i just downloaded it ill edit post with answer
ok the problem is the origin is under the ground so in w/e model maker just make it higher so that the rock is completely above 0,0,0 xyz or use the $origin command in the qc

Wow it was that simple? Thank you very much for your help.

I am clearly an idiot!
