For nobreath with classes:

class CWeapon
{
public:
	char unknown0[36]; //0x0000
	CTemplate* weapon_template; //0x0024  
	char unknown40[456]; //0x0028
	CDeviation* weapon_deviation; //0x01F0  
	char unknown500[4]; //0x01F4
	CBreathingComponent* weapon_breathing; //0x01F8  
};//Size=0x01FC(508)

class CBreathingComponent
{
public:
	char unknown0[20]; //0x0000
	float breathing_counter1; //0x0014  
	char unknown24[8]; //0x0018
	float breathing_direction; //0x0020  
	char unknown36[4]; //0x0024
	float breathing_time; //0x0028  
	char unknown44[8]; //0x002C
	float breathing_counter2; //0x0034  
};//Size=0x0038(56)

set breathing_direction = 0.0f; then with scope you have no breath!
