3DS Max: Revealing a Spline

[Dragen]

I recently watched a American Chopper commercial where a number of black lines seemed to be painted on the walls and floor. The lines were animated so that they looked like they were being painted as the commercial went on.

It looks like it was done with some sort of lofted spline that was either somehow revealed over time or they used an animated path constraint and some sort of lofting. Or something else, I don't know.

If anyone has seen the spot and has any idea I would love to get some imput. If you haven't seen it then my description was probably lacking, sorry.

Thanks.

If we are talking about the same thing.. it's MaYA

It's a composition between extrude along Curves, paint effects and partical flow along curves. And at a variaty of places curve extrusions where as the curves are set as emitters.

Not to a level I can guid you in Max ofr such a complex gather.

Ah, I see. I didn't think there would be a simple answer. Thanks anyway.
