I'm uploading a video to youtube that simply shows you the problem, but it's taking forever for some reason, so I'll edit this later with a link and just attempt to describe the problem now. Basically, there's a small section of my map that doesn't show up in game when you are standing in certain spots. When you stand in one area, it appears as if it has the nodraw texture, allowing you to see through it to the skybox, but if you move a little, it suddenly appears. This is obviously not what it should be doing, and I can't seem to fix it. I've tried using the compile log checker, but it doesn't find any errors. Here's how it should look: http://i920.photobucket.com/albums/ad41/BionicGinger/hl22011-07-1314-02-10-45.jpg Here's how it looks when you move to a new spot: http://i920.photobucket.com/albums/ad41/BionicGinger/hl22011-07-1314-02-04-95.jpg And here's how it looks when you stand right next to that angled ramp: http://i920.photobucket.com/albums/ad41/BionicGinger/hl22011-07-1314-02-21-17.jpg That last pic makes me think that the ramp has something to do with it, but I'm not exactly the most experienced mapper, so help would be nice, and if you need any more information, just let me know.
