I've been working on a new map of mine and have had some serious problems with only 1 thing...My floor seems to not hold my weight up. When I load my map I fall through and land on my skybox floor. I see the texture of the floor but just can't seem to stand on it. Ive tried deleting the floor and remaking a new one but no go. Anyone else have a problem like this and was able to fix it? Or maybe just have an answer for me?
Also, you may want to be sure that your floor wasn't made using caulk/nonsolid as it's base. If you did, you'd fall through, like water or fog. You need the standard caulk texture to hold you up.
Also a good note is if this is happening when u spawn make sure your info_player_start isnt in the floor, in the tutorial that i read it said make sure its above ground a little bit or your player can fall threw.
