Teddy sent me his map to see if I could get it working and compiled. Its was made as a UO map I believe, but as I dont have UO I just used normal CoD (UO ports straght back to CoD with only texture issues).
Ok, the problem, as always with no bsp files is the skybox. Very badly made. So I fixed it.
The good news is that it is fixed. Time for the bad news.
1. Whoever told you to use the caulk texture as a "clip" is wrong. Caulk is used for textures the player cannot see. Yes it works as a clip, but its not the way to do it.
Most of your map is now made from an invisble texture. Most textures are already clipped (only aphas and decals are not clipped). So, if you give something a texture, it becomes a solid object. Caulk is only used to save compile time (mainly). If you want an invisible texture in your map, use the clip textures found in the "textures/common".
2. Your whole map was made without using the "snap-to-grid". Bad idea, can cause errors. The 17th button from the left (looks like 2 right angles, red and black, with a blue cross) must always be on. Always!
3. Plan. What I can see from looking at the map in the edito, there is no route on which way to go. Then when I spawned in game, there was absolutely no where to go
This could just be because I cannot see the caulk platforms though.You now have 2 options for your map.
1. Start again.
2. Save this one from the dead.
More detail...
This map is full of objects made from caulk, I mean absolutely loads! You would have to use the snap to grid function and make each one slightly bigger, so it snaps to grid, then make it smaller, to get it back to size.
The map is way to big for a starting map, look at how Matrix is doing his, make it small.... then add to it.
If you are to start again, make a few things and send some screenshots of your editing process, so you can check it is being done correctly. This way you will get less errors, and you can also learn from your mistakes, and will not get any more similar mistakes further on down the lines.
This may sound stupid to a new mapper, but use some pen and paper action before you use the pc.
Get some plain paper, and sketch a rough 2d imagine of the plan. for eaxmple, how they will get from this place to another, where are the ladders going to be, slides.
If you want some more help with mapping, be sure to post up some questions. And if you do not get a reply on the forums quick enough, send me an email drofder(at)clanalias(.)com
