VFXWorld has an interview with some of the guys behind the effects of the new Fast & Furious film.
“It’s still very difficult for anyone in the effects industry, from ILM to us, to create absolutely realistic CG fire. We relied on a lot of practical fire elements that were shot but we integrated those with our CG smoke — marrying the two together seamlessly was the greatest challenge. We used a combination of Houdini and our own tools for the fluid simulations. We pushed our fluid simulation tools harder than we ever have. We’ve obviously done good water in the past, but repurposing those same tools to do fluid dynamics to this degree was a first for us.”
