Hello, TF2 mapping community! I'm Doctor Payne and Im looking forward to creating some maps and sharing them. I've only work with Hammer for a short period of time, but I'm addicted. Quick question: Could some one explain to me how to copy props from the "ultimate resources pack" into your map? I can't seem to open both files up on the same window of the hammer editor. And I can't copy and paste the prop from separates windows. Any help would be greatly appreciated. Cheers!
