The stereo team delivered 1,800 shots for ‘Monster Trucks’ in just six weeks, despite the challenges that the movie posed for conversion. The team ensured they had the elements packages for the CG to be able to use the z-depths as a starting point for the monsters and their crazy tentacles, really taking advantage of the 3D to exaggerate them.
The CG assets were useful when it came to the scenes with the monsters in the water. They glow a phosphorescent green on contact with water, which looks cool, and the team used the CG elements to deal with the depth in the water, setting up a layer for the water surface and creating depth from there.
There were lots of chase sequences in the movie. The trucks kick up dust, gravel and rocks, and the team spent time placing these elements in depth so that they appear to be flying out of the screen at the audience. Same for the manic sequence at the start of the film when the monsters first emerge from the ground. There were jets of oil and water flying everywhere and raining back down, and the team did a great job of setting the fluids and the debris in depth.
