Rodeo FX Bres Life into Jungle Animals for Tarzan

--

Rodeo FX completed nearly 200 visual effects shots for The Legend of Tarzan, including action sequences with CG hippos and crocodiles, where realistic water interaction was critical for the success of the shots. The studio's VFX work helped lift these animal sequences to a level where they look like scenes from a nature documentary. This is the first major production on which Rodeo FX has created CG creatures, adding to its repertoire of VFX skills.

Directed by David Yates, and starring Alexander Skarsg rd and Margot Robbie, Tarzan follows the title character, now living in London under the name Lord Greystoke, as he and his wife Jane return to the Congo on a government trade mission. When Jane is kidnapped, Tarzan returns to his roots to lead his animal friends on a rescue mission.

Rodeo FX created environments for the London set pieces, which involved 2D matte paintings, CG set extensions, and added CG vegetation. For scenes aboard a paddle steamer that were shot against a green screen, they stitched together background plates from a six-camera setup of scenery in Gabon. But it was the CG creature work that was the most challenging - and rewarding - aspect of the project.

Life-like Hippos and Crocs

Along with butterflies and leaf cutter ants, Rodeo FX created a pod of hippos, including one hero' hippo that attacks Jane, as well as a bask of crocodiles seen in the final sequence of the movie.

Because we built our creature pipeline from scratch, we had a great opportunity to do it right without legacy tools or workflows, said Mika l Damant-Sirois, CG supervisor at Rodeo FX.

Yates, along with his production VFX supervisor, Tim Burke, wanted the hippos and crocs to look aggressive and daunting, taking their cue from real animals filmed in documentaries. Visually, the animals were based on references of specific species of hippos and crocodiles and the team at Rodeo FX had complete freedom to develop the narrative aspects of these creature scenes.

Rodeo FX built skeletons and muscle rigging, skin, fur, and scales for the animals. Each individual animal was altered to provide contrast in such details as the crocodile scales, skin textures, and unique marks.

Rigging Creatures

The rigs were tested through animation cycles based on reference footage of movements the animals would make in the wild. These included resting on land and in water, walking, running, swimming, and fighting, during which textures and shapes would be pushed to the extreme and needed to maintain their realistic look.

The main hippo, which is shown in close-ups, required a separate facial rig that allowed us to control all the separate parts of its face, said Fran ois Dumoulin, VFX Supervisor at Rodeo FX. We had controllers for its eyes, which really brought it to life.

Water Interactions

Yates and Burke did not want to use stand-in models for the live plates - the traditional technique to obtain interactions with water and other elements in the scene - but chose to make the animal shots completely CG.

This meant we had to add interactive water and other elements to these scenes, said Dumoulin. This made the work even more challenging.

Rodeo FX used FX simulation to depict the animals interacting with water, debris in the water, mud, and sand. They made generic water that would mimic large amounts of liquid, then integrated CG water back into the plates. The water references came from three sources: the water tank in Leavesden provided water with no current or turbulence; a river in England with a slow current and ripples; and plates from a river in Gabon that had fast currents and lots of turbulence.

Tarzan was a milestone project for Rodeo FX. The intensive animal sequences allowed us to explore the combination of creature animation with FX work, said S bastien Moreau, president of Rodeo FX. The team did an amazing job meeting that challenge.
