1 Why I can't selec the models with pressing Shift +left_click? I have turned off something in Radiant?
2 Why can I walk through the model in the game?

3 How to be with sounds? For example:

or

I'm not sure about the sound aliases, but models don't have collision mapping in CoD4. Instead, they just used clip brushes on all the models and saved them as prefabs, So rather than using misc_model use misc_prefab.

the sound aliases are simple to fix.

for the AB one simple put in your update zone source:

sound,mapname,mapname,all_sp
sound,ab_battlechatter,mapname,all_sp

as for the other one in your own mapname.csv( make one if you dont already have in the "soundaliases" folder ) put this in it:

,,"If the first column for a row is blank, then the row is ignored"
,"If the first column for a row is blank, then the row is ignored",
# The first non-comment line of a sound alias file specifies the key name for all values appearing in this column.,,

"# This means it is safe to swap entire columns around, though you should never swap partial columns.",,
"# You can invent new keys, but the game will ignore them if it doesn't know about them.",,
"# You can leave out keys, but the ""name"" and ""file"" keys must always be present.",,

,name,name of the alias that is used to play this sound (required)
,sequence,"used to uniquely identify alias entries when more than one sound goes to an alias, used only to catch unwanted duplicates (default = 0)"
,file,the name of the file that contains the sound data (required)
,vol_min,"0 is silent, 1 is full volume (default = 1)"
,vol_max,"0 is silent, 1 is full volume (default = same as vol_min)"
,vol_mod,"blank causes no effect on vol_min and vol_max, otherwise the string must match a string in the volumemodgroups.def file and the value in that file corresponding to that string will be used to adjust vol_min and vol_max, clamped to the valid range"
,pitch_min,"1 is normal playback, 2 is twice as fast, 0.5 is half as fast (default = 1)"
,pitch_max,"1 is normal playback, 2 is twice as fast, 0.5 is half as fast (default = same as pitch_min)"
,dist_min,"within this distance in inches, the sound is always full volume (default = 120)"
,dist_max,"outside this distance in inches, the sound is not started.  If left blank or set to 0, the sound will play from any distance.  This does not affect sound volume falloff."
,channel,"auto, menu, weapon, voice, item, body, local, music, announcer (default = auto)"
,type,primed (a streamed sound which gets primed on some platforms) / streamed / loaded (default = loaded)
,probability,weight to use for the weighted probability of playing this sound instead of another sound (default = 1)
,loop,"whether this sound is ""looping"" or ""nonlooping"" (default = ""nonlooping"")"
,masterslave,"if ""master"", this is a master sound.  If a number, then this sound's volume will be multiplied by that number (a percentage between 0 and 1) any master sound is playing.  If blank, then neither master nor slave."
,loadspec,"space-separated list of which maps should use this alias; eg, ""burnville dawnville"".  If blank, the alias is used on all maps."
,compression,"a string corresponding to an entry in ""XMAUpdate.tbl"" which is used to determine compression by XMAUpdate.exe"
,secondaryaliasname,"defined the name of an additional sound alias to play in addition to the current alias being played. Note that it is an error for the secondaryalias to also define a secondaryaliasname (eg, if B is a secondaryalias of A, B is not allowed to have its own secondaryalias)."
,volumefalloffcurve,if blank uses the linear curve which can not be changed. A string 'XXXX' corresponds to the curve defined by the file 'soundaliases/XXXX.vfcurve'
,startdelay,defaults to no delay. The value is the number of milliseconds to delay starting the sound by
,speakermap,if blank uses the default speakermappings which cannot be changed. A string 'XXXX' corresponds to the speakermap defined by the file 'soundaliases/XXXX.spkrmap'. 
,reverb,"blank means the alias is affected normally by wet and dry levels, ""fulldrylevel"" forces the alias to use a full drylevel (ignoring the global drylevel), ""nowetlevel"" forces the alias to use no wetlevel (ignoring the global wetlevel)"
,lfe percentage,this determines what percentage of the highest calculated spatialized speaker volume should be passed to the LFE. blank means no LFE for the sound
,center percentage,this determines what percentage of the volume should be redirected to the center channel (equal percentage taken from all speakers).
,platform,"used by XMAUpdate to determine whether the alias should be processed for a particular platform.  If blank, process for all platforms.  Platforms are PC, XB, PS, WI.  Multiple values should be separated by spaces.  !PC will exclude alias from PC but include in all other platforms.  PC will only include alias for PC.  !PC XB is invalid."
,envelop_min,any sounds within this distance of the listener will use the full envelop percentage,,,,,,,,,,,,,,,,,,,,,,,,,,,
,envelop_max,sounds between enevlop_min and envelop_max use a fraction of the envelop percentage,,,,,,,,,,,,,,,,,,,,,,,,,,,

make sure you change all "mapname" areas are changed to your maps name.















models in game dont have collision period. you have to add it to them. The easiest known way is to put a clip around ur vehicle and when your done add a brush with the texture of origin. It should look like an orangy color with the word "orig" running across it. You can find it under the "tools" section in the textures.









For best results make sure you have the clips on the vehicle coveing it as u wish and the origin box is covering the exact same spot of the vehicles origin( the blue box, usually found under the vehicle). this way when they are link u know everything is exactly in place.















Now select all your clips and your origin brush and convert them to a script_brushmodel. Give ur brushmodel a targetname and Then you need a lil scripting do be done, where you link your script brushmodel to your vehicle and thats it. Heres wat the code should look like:

veh_col()
{
clips = getent( "veh_clips", "targetname" );
car = getent( "my_veh", "targetname" );

clips solid();
clips linkto( car, "tag_origin", (0,0,0), (0,0,0) );
}

as for not selecting your model i think u have pressed on the big "E" with the slash going across it on t he top of ur radiant. I think this should be of some use.

problem with the sound remained

which one?

Sorry. With sounds. Nothing has changed.

add me on xfire so i can help you. my xfire is "voidsource"
