Anyone know the best (i.e. fastest rendering) way to make a seamless "loop-
the-loop" track?

Render one frame.  That loops fairly smoothly.

Regards,
John

A bit more detail would help:-}

If you just mean repeating a series of images, then I would assume that you
would be better off looping them in an external application, rather than
waste rendering time producing identical bitmaps.

Beyond that, what John and Steve said.

I'm pretty sure this person meant a loop-the-loop as in
a track that goes in a loop.  i.e.  flips over.

Like the old electronic cars we had as kids?  on the
race-track?  with the triggers that would speed it up.

It would get to a point where it would go up...up...up
and around in a circle, upside down at one point?

some people call that a loop-the-loop, or loop-de-loop.

i.e.  from the side:   ___.O.____

If I'm right, you want to make a race track type loop?  up up up and around?

if so, a simple bezier patch might work.  If you use Moray, it has a
totorial
on how to make bezier patches...and in the tutorial, they show you how to
twist one into a twisted ribbon type shape.  If the array was big enough
length
wise, and you played with it enough, I'm pretty sure you could get a loop,
instead
of just a twisting ribbon.

might want to download the software (if you don't already have it), and
check it out.

Thanks John, I'm sorry I didn't explain what "loop-the-loop" track is.  
sOda figured me out, I meant a track loop, like in a roller coaster loop or 
actually more like the old "Hot Wheels" miniature car plastic track loops.

Good point, sOda figured me out though.

Yes, exactly!  Also like they used to have with "Hot Wheels" miniature car, 
a plastic track loop.  You let go of the car from the top of the track, it 
goes down and "loops the loop" without falling and continues down the 
track.

Yup, a race track loop, exactly.

Ok, thanks, I don't have Moray.  I'll check it out, but I think it's 
shareware.  I'll see if I can make a bezier patch mathematically first.
