From ILM:

Visual effects work on The Mandalorian was completed in all five of ILM’s studios (San Francisco, Singapore, Vancouver, London, and Sydney) as well as a contingent of other vendors under ILM’s supervision. The season’s 8 episodes encompassed nearly 5,000 visual effects shots in addition to all of ILM’s real-time effects work done for use during principal photography. The effects team leveraged virtually every trick in the book, from miniatures and motion control to traditional puppeteering, advanced animatronics, spectacular special effects, and photo-real CG. Here’s a sampling of ILM’s post visual effects work done for the series that garnered ILM 13 Visual Effects Society Award nominations.
