Okay so when anyone loads my map on their server only 1 player can spawn, if someone else trys to spawn it will kick them and come up with an error message "AimTarget_GetTagPos:Cannot find tag[j_head] on entity" how can i fix this?

here the .gsc file contents for the map:

main()
{

	maps\mp\_load::main();
	maps\mp\_compass::setupMiniMap("compass_map_mp_office");
	
	//setExpFog(500, 2200, 0.81, 0.75, 0.63, 0);
	//VisionSetNamed( "mp_office" );
	ambientPlay("ambient_map_ext");
	
	game["allies"] = "marines";
	game["axis"] = "opfor";
	game["attackers"] = "axis";
	game["defenders"] = "allies";
	game["allies_soldiertype"] = "desert";
	game["axis_soldiertype"] = "desert";
	
	setdvar( "r_specularcolorscale", "1" );
	
	setdvar( "r_glowbloomintensity0", ".25" );
	setdvar( "r_glowbloomintensity1", ".25" );
	setdvar( "r_glowskybleedintensity0", ".3" );
	setdvar( "compassmaxrange", "1800" );
}

I think that usually means the game is trying to use a non-stock player model that does not exist in either the map or the mod. But I could be wrong.

I found this while doing a Google:

AimTarget_GetTagPos: Cannot find tag [j_head] on entity


They are associated with not having the SAS vs Spatsnez "woodland" models compiled into your map.

That is also what the red "X" model is - missing assets.

You need to add the models to your map's zone_source CSV file:

include,mptypes_woodland

Then compile again.

i dont know what to type in the CSV file:/

try and see if something like this works

xmodel,nameofthemodel

example:

xmodel,body_complete_mp_zakhaev

This is a bug in CoD4, which has been fixed in some of the mods. Is there a mod running on that server ?
Also, post your zone file.
