1.open your mp_mapname.gsc located here rawfile,maps/mp/mp_mapname.gsc ,& add these 2 lines above maps\mp\_load::main();

maps\mp\mp_mapname_fx::main();
maps\createfx\mp_mapname_fx::main();
maps\mp\_load::main();

2.now if you have not already created an mp_mapname_fx.gsc
then just open the stock mp_bloc_fx.gsc
it should be like this
-----------------------------------------------------------
main()
{

level._effect[ "snow_light" ] = loadfx( "weather/snow_light_mp_bloc" );
level._effect[ "hallway_smoke" ] = loadfx( "smoke/hallway_smoke_light" );
level._effect[ "snow_wind" ] = loadfx( "weather/snow_wind" );

/#
if ( getdvar( "clientSideEffects" ) != "1" )
maps\createfx\mp_bloc_fx::main();
#/
}
------------------------------------------------------------------------
the words in red is the effect that will be loaded.
the words in green is the addres that the effect is located in the fx folder.
the words in blue needs to be changed to your map name fx gsc for example! mp_mapname _fx
once you have input the desired fx in the higlighted feilds
what fx you want RED /where it is located,GREEN /and changed the blue entry to your mapname fx gsc
click file save As ,then call it mp_youmapname_fx
now you have your mp_youmapname_fx


3.
Then create a new folder called createfx
in this directory raw/maps
& copy & paste the fx.gsc you just made in to that folder
open it up and deleate all the info in it
now just copy this info here in to it instead

----------------------------------------------------------------
main()
{
ent = maps\mp\_utility::createOneshotEffect( "snow_light_mp_bloc" );
ent.v[ "origin" ] = ( 1200, -464, 144 );
ent.v[ "angles" ] = ( 270, 0, 0 );
ent.v[ "fxid" ] = "snow_light_mp_bloc";
ent.v[ "delay" ] = -1;




}
-----------------------------------------------------------------------
using the original fx that was already there in the mp_bloc_fx .gsc as an example i have placed it in where it needs to go,the green numbers are the x,y,z location on your map where you want to place the fx

each time you want to add more fx all you have to do is copy & paste this ent info editing the red & green with what ever fx & location you want ,save & close that file once edited.

final step
open the compile tools click the update zone files button and add these 2 lines
rawfile,maps/mp/mp_yourmapname_fx.gsc
rawfile,maps/createfx/mp_yourmapname_fx.gsc
also add the relevant new fx
still using the snow_light_mp_bloc fx as an example
would look like this
fx,weather/snow_light_mp_bloc
then save !!!!!!!!!!!

build fast file every time you add new fx so do that now
then enjoy they should work and to prove they do look at my new fog fx
