I understand how the program works, how to place things, how to save things etc etc, but I'm not all that sure why these error messages are popping up. Maybe I'm dumb and am doing something wrong, and I apologize for my noobyness.
I'm sorry my posts aren't all that long, but I don't really know enough to provide paragraphs of information for you. I'm trying to go at this one step at a time in order to keep myself from being overwhelmed. On the bright side, I did figure out what I was doing wrong, and I facepalmed so ridiculously hard I still have a headache. The size for the NPC's were set to 0.0
This harkens back to my first statement, on the subject of noobyness.
As for the error messages that pop up, the two with 177 and 179.mdl point to my old install data\sfx\model. I'm not exactly sure what those are, but nothing seems to be out of the ordinary.
So I suppose, for now, all my errors are fixed. Thank you. ^^
