Find Child Entity Matrix All Messed Up - Bug?

[Shard]

I've been trying to parent the camera to the head of my character (after failed attempts with my model, I'm now testing with Crawler from the tutorial) and after some debugging, I've found that the position and rotation for the child head is all messed up. The Y and Z positions are all off.

 

This is code from the tutorial with my debug code in it. Using break points you'll see that the head pos and rotations are all off.

#include "engine.h" 

int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance,LPSTR lpCmdLine, int nShowCmd ) 
{
Initialize(); 

//Create a graphics context 
Graphics(800,600); 

//Create a world 
if (!CreateWorld()) { 
	MessageBoxA(0,"Error","Failed to create world.",0); 
	goto exitapp; 
} 

//Create a camera 
TCamera cam=CreateCamera(); 
CameraClearColor(cam,Vec4(0,0,1,1)); 
MoveEntity(cam,Vec3(0,0.85,-2)); 

//Create a render buffer for lighting 
TBuffer buffer=CreateBuffer(800,600,BUFFER_COLOR|BUFFER_DEPTH|BUFFER_NORMAL); 

//Create a spot light 
TLight light=CreateSpotLight(); 
RotateEntity(light,Vec3(20,45,0)); 
EntityColor(light,Vec4(2,2,2,1)); 
MoveEntity(light,Vec3(0,0,-5)); 
SetShadowmapSize(light,1024); 
AmbientLight(Vec3(0.1)); 

//Load the animated mesh 
TMesh mesh=LoadMesh("abstract::crawler.gmf"); 

TEntity head=FindChild(mesh,"Bip01 Head"); 


//Main loop 
while(!KeyHit(KEY_ESCAPE)) 
{ 

TVec3 pos2 = EntityPosition(mesh);
TVec3 pos = EntityPosition(head);
TVec3 rot = EntityRotation(head);

	if (KeyDown(KEY_LEFT)) { TurnEntity(head,Vec3(0,0.5,0));} 
	if (KeyDown(KEY_RIGHT)) { TurnEntity(head,Vec3(0,-0.5,0));} 
	if (KeyDown(KEY_UP)) { TurnEntity(head,Vec3(0.5,0,0));} 
	if (KeyDown(KEY_DOWN)) { TurnEntity(head,Vec3(-0.5,0,0));} 


	//Animate the mesh 
	//Animate(mesh,AppTime()/100.0,1.0,0,true); 

	UpdateWorld(); 
	SetBuffer(buffer); 
	RenderWorld(); 
	SetBuffer(BackBuffer()); 
	RenderLights(buffer); 
	Flip(); 
} 

exitapp: 
return Terminate(); 
}
