I’ve got a making-of video here for you to watch that offers a breakdown of the VFX work that was created for Spider-Man: No Way Home. It covers the compositing, the environment, the fx and digital hybrid suit work that was done by Imageworks.
As always, you might actually be surprised by how much of this movie was created using visual effects. There’s stuff you’d never things was CG. A lot of work went into making this film and the VFX turned out pretty damn impressive.
