The answer is, Industrial Light & Magic (ILM) Singapore worked on almost 200 shots including 155 full shots across eight sequences.
HereBeGeeks conducted an email interview with one of ILM Singapore's lead artists, Adam Lee, and he revealed some exciting details about Singapore's involvement.
"A large portion of the work was on the ocean battle sequence, where Gypsy Danger and Striker Eureka deliver the Warhead underwater to the rift.
"ILM Singapore did the entire sequence defining the look, showing the Jagears from above to deep underwater. We have to balance the visibility underwater and at the same time, try to show the scale and action of the Jagears."
Adam also revealed that they spent a total of 15 months working on the movie, and some of the Singapore artists were sent over to ILM San Francisco for training and bonding.
This was also the biggest, most complex and challenging project for ILM SG so far.
"Other challenges includes managing the resources for both rendering and storage. The water simulations requires alot of disk space and the renders of the Jagears and Kaijus takes days. In total we consumed 148TB of storage space just in Singapore alone. Despite the difficulty of the shots and tight deadlines, I think all the artists truly enjoyed working on Pacific Rim."
