This is a SourceMod plugin which allows you to change both world and view model of any weapon server-side. The plugin provides both a config file and a simple but powerful API for adding custom weapon models.

Changing the view model is not intended to be possible server-side, and therefore a bunch of dirty hacks need to be done in order for this to be achieved. See Requirements

• Counter-Strike: Source
• Counter-Strike: Global Offensive - Arm model also needs to be included in custom view model
• Day of Defeat: Source
• Half-Life 2: Deathmatch - Untested, but is expected to work
• Team-Fortress 2 - Not recommended, see Custom Weapons plugin instead.

• SourceMod 1.8 or higher
• A view model should work optimally if these requirements are met:

• Matching activities used by the original model
• More than one fire animation
• Contains an arm model (CS:GO)

##Adding a custom model in config The config file is located in the SourceMod config directory and is named weaponmodels_config.cfg

Inside the config you should find a key named "ViewModelConfig". Inside this key, add the following:

"<classname or item definition index>"
{
	"ViewModel" "<path to view model>"
	"WorldModel" "<path to world model>"

	"TeamNum" "<Team index>" // This will only allow the specified team to use the custom weapon. Teams index is usually 2 or 3
	"BlockLAW" "<1/0>" // This will block the look at weapon key in CS:GO, which may otherwise bug the view model
}

Note that you can just leave out any of the keys you wish not to use

Here is an example

"weapon_knife"
{
	"ViewModel" "models/weapons/v_my_custom_knife.mdl"
	"WorldModel" "models/weapons/w_my_custom_knife.mdl"

	"BlockLAW" "1" 
}

###List of weapons, class-names and item definition indexes

• Counter-Strike: Source
• Counter-Strike: Global Offensive
• Day of Defeat: Source
• Half-Life 2: Deathmatch
• Team-Fortress 2

The API consists of these natives:

native WeaponModels_AddWeaponByClassName(const String:className[], const String:viewModel[], const String:worldModel[], WeaponModelsFunc:function);
native WeaponModels_AddWeaponByItemDefIndex(itemDefIndex, const String:viewModel[], const String:worldModel[], WeaponModelsFunc:function);
native WeaponModels_RemoveWeaponModel(weaponIndex);

Full documentation of the natives can be found here

Here is an example

#pragma semicolon 1
#include <sourcemod>

// Don't forget the weaponmodels include!
#include <weaponmodels>

public void OnMapStart()
{
	WeaponModels_AddWeaponByClassName("weapon_knife", "models/weapons/v_my_custom_knife.mdl", NULL_STRING, WeaponModels_OnWeapon);
	
	// The item def index of the M4A1-S in CS:GO is 60
	WeaponModels_AddWeaponByItemDefIndex(60, "models/weapons/v_my_custom_m4a1s.mdl", "models/weapons/w_my_custom_m4a1s.mdl", WeaponModels_OnWeapon);
}

// Don't forget you can both share or have individual callbacks for weapons. In this case we share the callback
public bool WeaponModels_OnWeapon(int weaponIndex, int client, int weapon, const char[] className, int itemDefIndex)
{
	AdminId adminId = GetUserAdmin(client);

	// Player has an invalid admin id, don't show weapon
	if (adminId == INVALID_ADMIN_ID)
	{
		return false;
	}

	// Player is missing the specified admin flags, don't show weapon
	if (!(GetAdminFlags(adminId) & ADMFLAG_KICK|ADMFLAG_SLAY))
	{
		return false;
	}

	// All conditions have passed, show the weapon!
	return true;
}

Some weapons may be missing or invalid
