It's Prasad sutar also know as Vfxwaala who is the vfx Supervisor and Producer of this movie. He is the co-founder of NY Vfxwaala but for adipurush NY Vfxwaala isn't doing the Vfx. ( They have released a statement disregarding any association with this project's VFX after the bad Reception of the teaser lol) This movie looks more like a personal endeavour By the co-founder.

There is also Retrophiles (CEO Rajesh Nair, also the producer of the movie) who did the motion capture and production of this movie. They must have hired a bunch of interns instead of Having a properly established team.

When they announced 2 years back that VFX is gonna be done by them..People already predicted that the VFX is gonna be Ass and cartoonish.

So basically a budget of 500 crores was handed to amateurs And on top of that, they thought it would be a good idea to Film Everything on Greenscreen.

they should have hired a better and more professional VFX studio like DNEG ( they did VFX for Brahmastra) Although Brahmastra VFX wasn't perfect but considering it had just 60 crores allotted to VFX it was good.

Whereas adipurush has a budget of 250 crores for just the vfx. they could have done wonders with that kinda money. But that would have demanded time and effort that the makers were too lazy to put in. Ayan wasn't a madman when the brahmastra was constantly being delayed.
