Two assets I modeled for Dune might have gone unnoticed as being VFX additions.
One is the Baron's Suspensor Harness, which is the black tech on his back. I started from a 2D concept and made some design adjustments along the way. The other is a Digi-Double Head for Piter De Vries, which was used to slim his head down in post-production. There's a nice before and after in DNEG's "Beyond Sand & Spice" Deep Dive for the show.
