That particular shot of the baby using the Force to pick up the Mudhorn was the hardest from a CG perspective because it was such a big performance moment — its face was so concentrated.
We had a handful of shots of the Child where it wasn’t the puppet.
We were trying to make sure we didn’t do more than the puppet could do, and that we didn’t break what’s awesome and charming and perfect about the puppet.
Of course, the puppet does the heavy lifting in the show — the puppet is the baseline — but at that moment in time we were still figuring out what the puppet could do and how to get the best out of it.
