The film has Iloura serving as a principal VFX facility for the film with contributions including the albino rhino sequence in which the heroes  played by Dwayne Johnson, Kevin Hart, Jack Black and Karen Gillan get trapped in a ravine after their helicopter is damaged. The three must now find a way to outrun a herd of stampeding rhinos.

The sequence is almost entirely CG and among the most complex sequences in Iloura’s history. Explaining the same, Iloura VFX Supervisor Glenn Melenhorst said, “The ravine environment was completely CG, and in terms of sheer assets it was astounding. We had millions and millions of pebbles, boulders, trees, leaf litter, and so on, and every single element was built and rendered. We ran ground interaction simulations to determine how each individual asset would behave both in relation to the stampede and to the chopper blades kicking things up; plus we did simulations on dust swirling up from the ground and smoke rising from the chopper and coiling around the blades. And on top of these millions of environmental elements, we also had fully CG rhinos, a fully CG helicopter, and often, digital doubles of the cast.”

Working closely with director Jake Kasdan and production VFX Supervisor Jerome Chen to achieve the look, Melenhorst and team designed the ravine to contrast the lush jungle setting seen in most of the film.

A dry riverbed filled with crumbling rocks and decaying trees, the ravine offers a darker, more somber location. Through a combination of live action footage including a helicopter from the Hawaii-based set, and the cast sitting in a gimbal in the studio, Artists at Iloura digitally recreated the helicopter’s exterior and interior and created digital doubles of the leads as needed.

The VFX studio built its own digital doubles to achieve the fidelity required for close-up shots.

Iloura animation supervisor Nicholas Tripodi led the team in developing the look and behavior of the rhinos. Using real world rhinos as reference, artists ultimately created a hybrid look that incorporated elements from various rhino species, plus some creative liberties to fit within the fantastic video game world of the film.

In addition to the rhino stampede, Iloura also created VFX for the transitions in and out of the video game world, a CG waterfall and jungle set extensions, a digital matte painting for the reveal of Berber City and CG creatures including a vulture that appears across several shots.
