Ok. This has been on my mind for a while, and I havn't been sure if I should send this or not, in case I was being a bother. However, I decided to take a chance and send questions on how to do some things on hammer. I thought I could do ok without knowing this stuff, but my map is becoming less and less how I imagined it. Also, the official Valve tutorial has done a fat lot of good, not answering any of my questions. Anyway, here are some questions that have been bothering me. 1. The first, big one is how do you make a rounded world brush, i.e a circular platform? So far I have been making a square, copying it, turning it 36 degrees, copying it, turning it 36 degrees etc... There must be a quicker, simpler solution (I suppose there is displacement, but it is a bit too innaccurate) 2. The second question is how do you mirror your map so far, in other words to make a symettrical map? I don't mean copy it and turn it 180 degrees on the z axis, but to make an inverted copy of it, like Aerospace, not like Mach4. I hope you know what I mean.:unsure: 3. How do you put spectator cameras on your map? This isn't too important, but I may as well add it to the list. 4. I was once told to put something called cubemap on my map. I think this may be the most noobish question on the planet, but what is it? 5. Is there any way to get a valve map or an already made community map on to hammer so you can edit it? This would help me greatly find the codes to find certain things. I just wan't to say that this website has been brilliant for me, I have learned so much from here more than anywhere else. It's full of friendly people, and brilliant mappers. I only wish I could say the same about myself . Anyway, if you answer these questions, I promise I will try my best to make the best map I can:thumbup:.
