The Iranian based Alzahra Studio worked on the snake shots and two of the tiger sequences (18 in total) from the pre interval sequence of RRR.
Fun find: In the before image of second slider, you can see a 360 camera. This is used to capture what is called a HDRI (a high dynamic range image). It is captured to help give the fx artists lighting reference and sometimes is even used to wrap around a 3d model to match the surrounding lighting.
Fun Fact: Alzahra also worked on the Wild boar hunting sequence (creating the wild boars), Kunthala invasion sequence (creating Bulls, CG crowd, fire simulations, set extensions), most of the dam sequence (water simulations, CG double, 3d environment, set extensions) and a part of the climax from S S Rajamouli’s previous film, Baahubali 2: The Conclusion.
