Flashplayer 10.  
I have clip A in library containing clip B that has some 3D parameters applied to it (rotation etc).  
I place clip A on stage and run movie. Nema problemas.  
But. If I connect clip A to a custom class (clip B is a public property of that class), all the 3D settings of clip B is lost.

Does anyone know why and how to get around this?  
Do I have to set all the same 3D parameters in code?

EDIT: Tried to set the container (clip A) to extend MovieClip instead of Sprite and it worked!? 3D parameters are intact.  
If anyone understands why I’m interested to know.
