After workin on a map for a while, (a week) radiant decides to come along, and delete all but a few random meshes and brushes *My poor trains* This is the second time it has happened to me, both on quite mesh-comprehensive maps. Luckily I have a previous .bsp, but i now have to sort through the rubble
I was just wondering though: Does anybody share this experience? and is there a way to stop it happeneing?
do you have use quake 3 .map format checked in preferences ? If you do uncheck it . It didn't happen to me but it did to someone I know . When they had that checked and set a surface parm then every thing stopped showing up after the brush with the surface parm . If you open you map in notepad and look it maybe that every thing is still there and there is an error with one brush . If that is it you can also delete the bad brush . If you look at edit->mapinfo it will tell you how many brushes in the map and if you open it in notepad and go to that brush it maybe the bad brush . I think one bad brush will also stop every brush after it from showing in radiant .
I have seen it before and it was an error in the text of the .map file. The error was a pair of quotes I had put around a trigger message value--radiant does that too, so I ended up with double quotes. That bad line stopped everything below it from loading in radiant. And, there was a small untextured box near the center of the map.
I fixed it by opening the .map file in Wordpad and removing/replacing entities until I found the problem.
