I neglected to post on the forums to answer some questions, but I decided now to give up and ask. 1) Could someone point me to a guide on how to make and install props into hammer? I know how to 3D model in Blender, but since it was for 3D-printing, I never learned texturing. 2) Is it okay to use mostly props that were purpose-made for other maps? Or is it a good idea to make my own just for originality's sake? 3) How do I get my skybox to look like the one on koth_sawmill? I used the alpinestorm preset from the sky list, but it looks different and the half below the horizon is messed up. My map overlooks a cliff, so that's a problem. 4) Logic problem: I have a basement with lights that turn on when you walk into it. I also want the lights to turn off when you leave, but on a delay. (3s or so.) The problem is that, with my current setup, if you exit the room and immediately re-enter it, the lights will flicker off and on 3 seconds later. (Because the output to turn the lights off is still queued.) And if the delay for turning off the lights is longer than the delay for turning them on, this will cause the lights to stay on, then turn off completely after the 3 seconds. Any ideas for how I could implement this system? 5) My map is a King of the Hill map, so it is symmetrical. I had the idea to make the basement asymmetrical. The basement's only entrances are on the center divider line of the map, so neither team has an advantage for getting to the medium ammo pack inside any faster. The only possible way I could think of for this giving either team an advantage would be for the targeting with the Scottish Resistance or Wrangler through walls. But that seems like a stretch. Is there something I'm missing or is this okay? 6) I have a lighting issue. (See attached photo.) That line is where two displacement "plates" meet. (Two brushes stitched together.) Is this common? How do I fix it? 7) In a symmetrical map, is it okay to have a blue prop on both sides of the map? Or does the red team's side need to have a red version of it? (e.g. wildflowers, watering cans) 8) What are cube-maps, why do I need them, and why does my map seem to look fine without them? (And how do I use them?) Sorry if this post was too long, but I would seriously appreciate any help! Thanks!
