Updated main post. On to a dilemma:
Props. Unfortunately, the props for HL2 weren't designed to fit into a clean, space station environment. I'm faced with either settling for them, or completely redesigning and implementing new props to be used. The obvious upside is that the map would be more awesome and cool, with the downside being filesize and download times. I want to know whether you would all mind having a possibly 60-70mb (guesstimation, really no clue how big it would be) map hosted on your server. I've never made a ZS map before, and I'm no coder, so I'm not sure if the props must have health set in the code or if their health is related to weight or what is going on.
In the meantime, I'm going to begin modeling everything anyways, and if worse comes to worse I'll simply release two versions of the map. One with, one without. If anybody has any information about this, please let me know as I won't be compiling the models until I find out.
