This is best suited for a compositing system that has a tracker.
Render an object to be tracked (eg; your null), then import that sequence
into a compositor. In the compositor import your sprite image and apply it
to the tracked object. Specifics how to do that vary with the compositing
program of choice. Might be able to use Byron's old XSI to AE script to
dump the position information of the null if necessary.

Hi yall....
I have a null in my scene.
I want to constrain a bitmap to it and always have it face the camera.
I know how to do this, position constrain grid with texture to null, orient
constrain grid to camera, blah blah. But I want to maintain a grid size
that is screen relevant not scene relevant. So I don't want to do this old
school.
Instead I'd like to attach a sprite to the null instead, have it render a
set pixel size instead of a world space size, but I don't really want to use
ICE or particles since it's only a single object, that just seems overkill.
Is there a simpler way to accomplish this kind of thing?
