It's not because of my texture. I have this problem with all transparent textures
I will start with the mapfile. You have a sky, so I would prefer a sun lighting instead of light entities (without a source). It looks way better. Just delete all light entities and add the following default keys/values to the worldspawn.
"_sun_light" "250"
"_sun_angle" "150 -34"
"_sun_ambient" "30"
"_sun_diffuse" "60"
There are very high walls in your map. I guess you have to use another (more high) angle for the sun. You can play with the second number.
Delete "value" "3" from the two second flags to fix the message while loading the map.
The rest looks good here. So I will come the the map itself now.
The reason that the cave under your map isn't fixed 100% are many small holes in your map. Some of them will be fixed if you have fit the ends of this transparent brushes. The other ones should be fixed for the next beta. Later I will show you a few screenshots that you can see where the holes are. I can help you if you can't find and fix the last ones. But try to fix it by yourself first. Maybe it will be helpful to delete all the brushes under the map, because you could use the leak check afterwards. Btw you can avoid this holes very easy, if you don't map with the <16 unit grids. Please don't shock me again with such a disordered map
Also there are lots of misaligned textures (all wood textures and all barrels; set all values for the rock texture to 0 to fix misalignments here) and missing brushes. I will add screenshots to show it, too. Have a look at the following textures though. The brown ring should be the lowest one.
Your barrel textures are not the same. But this doesn't make a big difference, they are misaligned
. The barrels ingame has to look like the texture did. It's just easier to align with this textures maybe.
I think you know my opinion about second flags. Hmm...but it might be ok in this map. The placement could be a good choice.
The only thing I really hate are the spawnrooms. It would be more nice when the people would spawn all over the map/base and not in parts of maps, where the spawnrooms are easy to line. Remembers me on propaint. It's very boring sometimes...
And the biggest part with screenshots now (you have to fix the things on both sides of the map). You have to work a lot on this map. Sry that i don't post the screenshots here, but I don't want to upload so many files. I wrote the comments into the screenshots if necessary.
http://www.mediafire.com/?ehbdeso08onhqbdI'm sure that this isn't all. Fix the things I wrote about and then I will have a look at this map again.
