Elastic Reality, blast from the past! Most big compositors have morphing built in, Flame, Shake and Combustion all do. Not sure if there are any other standalone tools any more, it’s a bit passe 😉
I’d be interested to know how old ER compares to things like the new Flame Distort node from people who’ve used them lots… I notice that the old Avid Media Illusion warper is just piles and piles faster than Shake’s built-in one, which I guess is not accelerated.
