Alrightie, I've just recently delved into the mapping scene, and I'm right now taking on a rather big project for a newb of mapping (making my college campus, 'cause it'd be a really great Atk/Def CP map). I have some other smaller projects on the side, but that's not the point at hand. I'm making the buildings of my campus separate from each other first, then putting them together after making the basic landscape. Slightly unrelated, but is this a good idea or would it be better to put them all in one file (mind you the first is more practical and organized, but - hey - I dunno). Now, finally, getting back onto the matter at hand: Hammer crashes/freezes in the middle of compiling. I looked up what some reasons could be, and - as per the Valve Wiki article - I went over my work, and found some misplaced, overlapping brushes and such, so I got rid of them and fixed some other design flaws. However, it's still not compiling before it freezes. I'd be happy to get more specific, but if there's some general things I should double check, please lemme know. Thankies.
