Fascinating! Apparently I've been out of the loop on the animation software biz for a while (not surprising), as apparently DIsney Animation had transitioned over to using Pixar's "Presto" since Zootopia 2!!! 😱
* Disney Animation have famously previously been a Maya shop. (IIRC, since that year 2000-ish "Dinosaur" film)... "Autodesk Maya"... yeah... Blenderheads who've followed my work for many years know my thoughts on that thing!
Other famous "Maya shops" include:
* Blue Sky
* Weta
* ... and a whole bunch more, as for many years, it was generally considered the "Industry Standard" (mainly due to its plugin API making it modular + extendible over its expensive proprietary DAG-graph core)
* Pixar's "Presto" is an in-house animation software they starting rolling into production from around 2012 (i.e. IIRC, they started using it with the production for "Brave"?).
It replaced the "Marionette" tool that they had been using for all their "Golden Age" films... which AFAIK owes its heritage to the pioneering tools from the 1980's the Lasseter + co used to animate classics like "Wally and the Bee" and "Luxo Jnr"
* Of a similar vintage is Dreamworks' "Preemo", which superseded a really primitive thing called "Emo". (This one famously had its first outing on the HTTYD2 film, where all its parallelism and spiffy realtime performance and so forth was really able to be shown off!
