deformation Model deforming when rotating.

[npmproductions13 14]

Like my title suggests I'm making a weapon for the first time and I want the barrel of my minigun to turn in place when firing. Currently it turns but deforms beyond recognition when rotating but returns to normal when the rotation reaches 0 again.
This is the animations class of my model.cfg. I can't see anything wrong with this.

class Animations
        {
			class barrel
            {
                type="rotationZ";
				source="ammoRandom";
				sourceAddress="loop";
				selection="barrel";
				axis="barrel_axis";
				centerFirstVertex=1;
				memory = true;
				minValue=0;
				maxValue=0.5;
				angle0="rad 0";
				angle1="rad 180";
            };

parenting issue / meshes across multiple named selections. paste the entire model.cfg

[npmproductions13 14]

This was the first animation class I've added I still need to work on the magazine_reload etc.

Here's my model.cfg so far.

class Rotation;

class CfgSkeletons
{
    class Skeleton
    {
        isDiscrete=0;
        skeletonInherit="";
        skeletonBones[]=
		{
			"ammo_box", "", 
			"barrel", "", 
			"camo1", "", 
			"camo2", "",
			"camo3", ""
		};
    };
};
class CfgModels
{
	class Default;
    class IA_minigun: Default
    {
        htMin=0;
        htMax=0;
        afMax=0;
        mfMax=0;
        mFact=0;
        tBody=0;
        skeletonName="Skeleton";
        sectionsInherit="";
        sections[]={"ammo_box", "barrel", "camo1", "camo2", "camo3"};
        class Animations
        {
			class barrel
            {
                type="rotationZ";
				source="ammoRandom";
				sourceAddress="loop";
				selection="barrel";
				axis="barrel_axis";
				centerFirstVertex=1;
				memory = true;
				minValue=0;
				maxValue=0.5;
				angle0="rad 0";
				angle1="rad 180";
            };
        };
    };
};

why is there camoX in your model.cfg? does it serve any purpose as a bone?

pretty sure there are shared vertices between camo selections and your other selections

[npmproductions13 14]

No there isn't a reason to have it there I was under the impression you just had to label all selections as bones but obviously I'm wrong. I'll try removing those later this week.
