Compiling is making my map revert to an old stage - Developers

I'm getting this weird problem with my Source SDK when I compile my map, I finished my map today and when I try to do a full compile it takes 2 minutes then it goes ingame but it only shows an area I was working on with the cordon tool. I turn it off and everything but it still runs in that same area. I have no clue why. Thanks in advance.

I've had this problem before and this is how I fixed it: If you have a HUGE displacement brush somewhere on the map, try taking it and dividing it up into 4 displacements sewn together. For some reason, huge displacements don't work sometimes and you have to "chop" them up for them to compile right... This might also be the same with brushes although I can't remember.

I do have displacements on my map and I have tested them before with cordon tool with no problems.

OK do this for me: Do a compile with everything on "Normal" but put VRAD on "No" and see if your map compiles with the updated version (although without lighting) This will be able to tell me if the problem happens in VRAD

Try copying everything over to a new map

Show us the compile log

you probably got one of those space-time-quantum-slip-space-anomalies. A.K.A a leak

Seems like it's not overwriting a already placed bsp. Try renaming the vmf to _1 or something without spaces and recompile to get a fresh bsp. I used to have a problem where whenever i compiled it wouldn't overwrite the bsp in the main folder so my changes never took effect. Try it but give more details not much to go on.

Okay, I just renamed it and compiled and it said this: ** Executing... ** Command: "c:\program files\steam\steamapps\mrtorchic\sourcesdk\bin\orangebox\bin\vbsp.exe" ** Parameters: -game "c:\program files\steam\steamapps\mrtorchic\half-life 2 episode two\ep2" "C:\Program Files\Steam\steamapps\mrtorchic\sourcesdk_content\hl2mp\mapsrc\space_station_1.vmf" Valve Software - vbsp.exe (Jul 7 2010) 4 threads materialPath: c:\program files\steam\steamapps\mrtorchic\half-life 2 episode two\ep2\materials Loading C:\Program Files\Steam\steamapps\mrtorchic\sourcesdk_content\hl2mp\mapsrc\space_station_1.vmf ConVarRef mat_reduceparticles doesn't point to an existing ConVar Could not locate 'GameData' key in c:\program files\steam\steamapps\mrtorchic\half-life 2 episode two\ep2\gameinfo.txt Patching WVT material: maps/space_station_1/pk02/pk02_rock01_ground01_blend_wvt_patch fixing up env_cubemap materials on brush sides...

(3625 prims, max 32768 :: 65538 indices, max 65536) Description: (from Jeff Lane, Valve) "VBSP does cleanup of edges where func_detail geometry meets world geometry to avoid getting visual cracks. One of the ways it does is this by elminating t-junctions. It sounds like you may have hit a limit of the number of those cleanups in the level. Solution: If that is the case, you could fix the problem by reducing the number of func_detail brushes in the level, especially ones that touch non-detail geometry. It's probably a sign that you have too much complex brush geometry in the level, and would benefit from having some of it be model geometry instead." The error message shows you that you have 3625 primitives (max 32768 causing all of this, resulting in 65538 t-junctions (max 65536)[/quote]

Had a feeling it was something to do with that. Is there a quick way to get rid of them or do I need to manually remove them all?

Just select the func_detail then in the 2d viewport right click on the selection and go "move to world" should work.

Okay, I went around the map and removed alot of func_details. I think it works as it takes longer than the 2 minutes it did before. I'll compile it later when I go (it'll take a long time) to keep you guys updated if it worked.

You could try making models.
