Hi all.

Have come up against a prob whilst attempting to put a 2D image into a
3D  scene.  Basically, I want a shadow underneath a flying craft, and I
figured it would be more effiecient to use a sprite that followed the
craft (3D model) on the ground (also a 3D model).  I can display, scale
and move a sprite on its own, but when I put the code into the 3D
program, the sprite is not displayed, although the 3D models appear and
move about as normal.  I have tried sending the sprite to the ordering
table first, last and in between the two models, but to no avail.

The sprites priority is set to 0, which I thought would make it on the
top layer.  All the loading of the image and the sprite attribute set up
functions seem to be working fine, its just that nothing appears on the
screen.

Does anyone know if it is possible to combine 2D and 3D in this way?  Or
failing this, if I have to resort to a 3D shadow, if its possible to
scale a model (not very relevent to 2D,  I know).

Cheers,   Anna.
