Hasta La Motion!

I’m looking into the role of a Previs artist and Layout TD. Do these artists have the same role?

In some job summaries, a Previs artist works with the Director and VFX Sup by providing previs, post-vis, camera and character blocking in 3D which shows the early shot sequences of a film.

Is the Layout TD merely responsible for creating pipeline scene assets to be used in set extensions, UV mapping for compositors and integration of 3D animation for the 3D/CG Department?

If this is not the Previs artist’s job, then does the Layout TD do the previs as well as provide pipeline scene files?

Hope to hear some good answers!

Thanks
