HELP! - I need help... with QuatF...

So I'm like in the last phase of my please rewrite but i have an issue.

Apparently you can not rotate the root node of a animation applied to a character that has animations for its root node.

Which leaves the hard part to make swim animation where i can rotate the center node in a 360 axis.

But at the same time rotate the swim animation forward 90 degrees.

I built 2 QuatF on to translate the Z rotation and one to rotate the x axis 90 degrees.

I want to merge these to make one transform but when i try i get some kind of weird scale on my character.

//CHANGE FOR NODE ROTATION

		Point1.y=10;
		Point1.z=0;

		Point2.x=10-(move->y);
		Point2.y=10+move->x;
		Point2.z=0;
		
		//(CalcTheta(Point1,Point2)*180)/M_PI_F; // angle in degrees
		mDataBlock->DIR_ANGLE = CalcTheta(Point1,Point2);

		Point3F _pos;
		_pos.set(0,0,0);

		Point3F _axis;
		_axis.set(0,0,1);

		Point3F _SWMaxis;
		_axis.SWMset(0,1,0);
	
		QuatF _rot;
		QuatF _SWMrot;

		F32 y2 = move->yaw/2;
		if (y2 > M_PI_F)
		y2 -= M_2PI_F;

		mDataBlock->DIR_ANGLE-=y2;

		if (mDataBlock->DIR_ANGLE <0)
		mDataBlock->DIR_ANGLE += M_2PI_F;

		_rot.set(_axis,mDataBlock->DIR_ANGLE);

		_SWMrot.set(_SWMaxis, ((90*M_PI_F)/180) );

                //Test 1
                //_rot+=_SWMrot
