Hi Michael,
If you want to have a series of layers of 2D and 3D content then you
simply set up you Camera's with an appropriate RenderOrder number, the
ordering goes :
PRE_RENDER, from negative to positive RenderOrder number
POST_RENDER, from negative to positive RenderOrder number
In your case you 2D background you'd probably just draw with a
PRE_RENDER, the 3D as defaults, and the 2D foreground as POST_RENDER.
The only other item you'd need to tweak is that the clear of the
colour buffer on the 3D and 2D foreground Camera's should be disabled.
Robert.
