I am trying to use rotationY,X,Z on an externally loaded image. The image is displayed properly when no 3D rotation is applied, but does not appear afterwards. I have tried various things: loading the image into a bitmap, loading that bitmap into a Sprite/MC. What am I missing?

Just to be sure, regular rotation works fine, e.g
PHP Code:
pic.rotation = 2; 
....axis rotation does not
PHP Code:
pic.rotationY = 2; 
Thanks,
