Animatics in Sketchup helped the director choose angles to shoot.
The Big One is a short film about a cult that throws people into volcanoes to create earthquakes. They are trying to create the eponymous "big one", an earthquake that would destroy the world.
I was tasked with creating the visual effects for sequences involving the volcano and lava pits. I utilized a variety of concept art and animatics to visualize the sequences, and built miniatures of rocks, volcanoes, and lava pits, and filmed them against a green screen for compositing.
