i want to do an interface to my application, some buttons, hp bars and so on… as have projects in the showcase… i am going to use sprites, but they must be added to mesh first, so the way it should be:
-create plane mesh;
-arrange it in front of camera;
- (because my camera is rotating and zooming) i also should “bound” plane mesh to my camera, rotate ans scale it the same way, to locate my interface always in the same place of screen…
i wonder if it is more simple way to do, like text3d, that is always on the screen, maybe there is a way to add sprite to TextField3D or some other way…

Why you dont do direct on the layer?

You don´t need to do this in 3D. Simply put the stuff you need into a sprite and add it to the stage.
Stage3D will always be under your sprite as standard flash content is always placed on top of it. And the camera only affects the Stage3D stuff.
