This is only possible via script commands e.g.

Level.CreateWorldItem( "wear:EmbassyAgent_1" , "equipment" , 821.00, 4.00, -368.00, 0.0, 0.0, 0.0, 'id_wear1' );

1. "wear:EmbassyAgent_1" is the item you wanna spawn, the
   item names you can find inside the equipment.shadvs, weapons.shadvs etc.
   
2. "equipment" is the library (class) name. Same as shadvs files I mentioned above
   
3. 821.00, 4.00, -368.00 are the coordinates (x,y,z). You
   can aquire the current position via console command:
   pl_showpos.
   
4. 0.0, 0.0, 0.0 I dunno, let it as it is
   
5. 'id_wear1' is the id of the newly created item.
   Necessary but not used in case of spawning.

Update:

• I've been proof-reading all the Level LUAs.
• I also changed a failed mission script from "Diplomat has been killed" to "Diplomat has been attacked", because if you knock him out, it's still classed as killing him.
• It's now possible to steal the utility room key from one of the waiters without taking him out.
• I added in a key to the diplomat's safe to save players from picking the lock. It's in the possession of the kissing guard.;)

In regards to wanting to place new clothes, I want to place a warden's uniform on the bed in the room near the conference hall in "Stronghold" to start with. AHO, can you please give me the coordinates of said bedroom?

You can aquire the current position with the console command PL_ShowPos.

Have I done this right?

Level.CreateWorldItem( "wear:GermanYellow" , "equipment" , -60.064407, 0.906136, 555.986816, 0.0, 0.0, 0.0, 'id_wear1' );

This seems correct. But I did not test it. Are the new clothes shown
correctly? Maybe you have to correct the y-coordianate manually.

Note: the id at the end must be unique, so if you create another
item via this command it must have a different name.

PS: Why don't you post some screens shots of your work,
I'm very interessted in your results...

They don't show up, and I'm trying to place them on the bed like what you did. How do I manually adjust the y-coordinate. And as a confirmation, is "GermanYellow" the warden's uniform?

It is not shown? Then you did something wrong

1. The game engine makes strange things, sometimes the spawned
item is in or under the ground. So try to change the y-coordinate
manually (the digit)
2. Just change the Number
3. Yes it is, just search in folder \players\ for the file if you are not sure

I got the warden's uniform to show up on the bed, but there's something wrong... I think I made up to three duplicates of the uniform in the same position.:grin:

How do I only make one warden's uniform appear on the bed instead of multiple uniforms in the same position?

Also, I tried to add a chef's uniform in the Embassy kitchen. However, when I attempted to test it, the level loads with Strogov in his camouflage clothes, without his weapons, under fire.

Use one command Level.CreateWorldItem("wardenUniform", ...) instead of multiple.

Very strange. Is it a result of Level.CreateWorldItem("chefUniform", ...) command? Or you was trying to modify SWD file using hex-editor?
