More of a question than a request

Basically I just wanted to know what various purposes or programs most people come to Modeler's Resources for. If I could mess-about with a set of models in Blender or Maya that'd be cool.

AFAIK, people usually use the models in the Model Resource for making games, animations, renders, and porting to other games/programs like MMD, Garry's Mod, or Source Filmmaker.

It's very broad of you to assume I know how to write a QC file--let alone know what that is--or even compile something. In fact, all of what you said is beyond my talent or skill level.

Then, I highly recommend you check out the Valve Developer Wiki if you just starting out in Source porting.

Here's some information about qc files and compiling a model.
