Issues with BitmapData of a MovieClip with rotationY applied to it - actionscript-3

Question

So I have a simple file right now that eventually will take a movieclip and save it as an image. I am currently rotating the clip's y by 45 to give it kind of a 3D look and adding it back to the stage. I've tried googling and a couple different things, but I can't quite get it to work. The first thing I tried was getting the BitmapData of the movieclip I rotated. That flattened the clip:
test_mc.response_mc.rotationY = 45;
var mc:MovieClip = test_mc.response_mc;
var bmp:BitmapData = new BitmapData(mc.width, mc.height);
bmp.draw(mc);
var output:Bitmap = new Bitmap(bmp);
output.x = 270;
output.y = 191;
addChild(output);
The next thing I tried was getting the parent clip's BD. That gave it an angle... just the wrong one:
(same code as above with this line change)
var mc:MovieClip = test_mc;
Any thoughts here would be nice. I tried doing stuff with matrices, but had no luck. I also have images... just can't post them yet :(
Something else I've tried with no luck:
var target:DisplayObject = test_mc as DisplayObject;
var targetTransform:Matrix = target.transform.concatenatedMatrix;
var targetGlobalBounds:Rectangle = target.getBounds(target.stage);
var targetGlobalPos:Point = target.localToGlobal(new Point());
var targetOriginOffset:Point = new Point(targetGlobalPos.x - targetGlobalBounds.left, targetGlobalPos.y - targetGlobalBounds.top);
targetTransform.tx = targetOriginOffset.x;
targetTransform.ty = targetOriginOffset.y;
var cloneData:BitmapData = new BitmapData(targetGlobalBounds.width, targetGlobalBounds.height, true, 0x00000000);
cloneData.draw(target, targetTransform);
var output:Bitmap = new Bitmap(cloneData);
**Another update**
So hopefully this will help a little. I was able to recreate what I was doing using Matrix3D.
test_mc.response_mc.rotationY = 45;
var matrix:Matrix3D = new Matrix3D();
matrix.prependRotation(45, Vector3D.Y_AXIS);
test2_mc.response_mc.transform.matrix3D = matrix;
test2_mc.response_mc.transform.matrix3D.appendTranslation(0, 0, 0);
And I've come closer to getting the bitmap to look correct (thank to a Mike Chambers blog).
var mcOffset:Matrix3D = test2_mc.response_mc.transform.matrix3D;
var rawMatrixData:Vector.<Number> = mcOffset.rawData;
var globalBounds:Rectangle = test2_mc.response_mc.getBounds(test2_mc);
var matrix:Matrix = new Matrix();
matrix.a = rawMatrixData[0];
matrix.c = rawMatrixData[1];
matrix.tx = test2_mc.response_mc.x - globalBounds.x;
matrix.b = rawMatrixData[4];
matrix.d = rawMatrixData[5];
matrix.ty = test2_mc.response_mc.y - globalBounds.y;
var bmp:BitmapData = new BitmapData(150, test2_mc.height);
test2_mc.response_mc.transform.matrix3D = null;
bmp.draw(test2_mc.response_mc, matrix);
test2_mc.response_mc.transform.matrix3D = mcOffset;
var output:Bitmap = new Bitmap(bmp);

Answer 1

Well I took it a step further back and went to the stage. For whatever reason trying to draw the parent (test_mc) of the rotated movie clip (response_mc) WON'T work, however drawing the stage and setting the bounds to the area of the parent DOES work. Here's my code (which is sadly very simple):
var bmp:BitmapData = new BitmapData(test_mc.width, test_mc.height);
bmp.draw(stage.getChildAt(0), new Matrix(1, 0, 0, 1, -test_mc.x, -test_mc.y));
var output:Bitmap = new Bitmap(bmp);
