Hello there! I have gathered a couple questions that I need answers for. 1. how can I take an official map (like 2fort) and make it usable by hammer.exe? 2. Is there a way to place down already chosen props? (Like a brush or some sort) it would save a lot of time 3. How can I make payload tracks? I don't see them anywhere 4. How do I make trains that actually work? (Like on the official maps) 5. When I make a map, where do I publish it? 6. How do I make a spinning hazard? (Like a laser that spins) Thanks!
