Okay, first off all, this is not for TF2 (It's for half-life/Garry's mod), but I REALLY need help, and since this is an awesome map forum, I decided to make the topic here. To the problem, when I add props in hammer editor, just a few of them shows up in the map itself. I made about 30 props in hammer, and only one of them showed up. The props is from the same game. The prop the shows up and the props who doesn't. This has also happened to me in a TF2 map I made. Please help. I really need it.
