Cannot load material file __charcoal_.002, what does this error mean?

[VonNexus]

Hello guys, basically I have made a soldier model (created after the nice ARMA 2 Russian Soldier model released by BIS) l with Blender and then exported it in the .p3d extension thanks to a plugin posted in the forums. No problems when I open it in Oxygen 2, it all works like a charm. Before working with the textures and improving the model, I'd like to see how it's rendered in ARMA 2. I've created a very poor addon folder. In it, I've got the .p3d model (called CC_riotcontrol_1) , the config.cpp, a model.cfg and a texHeader.bin (which I didn't create, I suppose it's something that came out when I firstly converted the file in the .pbo extension with BinPBO) .
The config.cpp is at it follows :

#define true	1
#define false	0

class CfgPatches {
	class CC_riotcontrol_1 {
		units[] = {"CC_riotcontrol_1"};
		weapons[] = {};
		requiredVersion = 1.0;
		requiredAddons[] = {};
	};
};

class CfgVehicleClasses {
	class CC_riotcontrol_1 {
		displayName = "Test CC";
	};
};

class CfgVehicles {
	class All {};
	
	class AllVehicles : All {};
	
	class Land : AllVehicles {};
	
	class Man : Land {};
	
	class Soldier : Man {};
	
	class Civilian : Man {};
	
  class USMC_Soldier_Base : Soldier {};
  
  class USMC_Soldier : USMC_Soldier_Base {};
  
  class USMC_Soldier_Light : USMC_Soldier {};
	
	class CC_riotcontrol_1 : USMC_Soldier_Light {
		vehicleClass = "CC_riotcontrol_1";
		displayName = "CC RIOT";
		model = "@test\CC_riotcontrol_1.p3d";
		
		class Wounds {
			tex[] = {};
			mat[] = {"ca\characters\heads\male\defaulthead\data\hhl.rvmat", "ca\characters\heads\male\defaulthead\data\hhl_wounds.rvmat", "ca\characters\heads\male\defaulthead\data\hhl_wounds2.rvmat"};
		};
	};
};

When I start up the game and get in the editor no problems. I place the soldier and perview, it loads up and suddenly an error shows up: Cannot load material file __charcoal_.002
I don't know what the hell this error is. The word "charcoal" doesn't show up both in the config.cpp and in the model.cfg . So where the hell is it from?
Any help would be very appreciated, thanks in advice!!!

Seems very likely you have the file "__charcoal_.002" mapped to your Blender model (hence the p3d file.

Have you looked at all face mapping in O2? Both texture AND material.

By the way I think maybe

model = "@test\CC_riotcontrol_1.p3d";

is incorrect. Suggest dropping the @
