See amazing demo videos of Wētā FX’s in-house simulation tools
Wētā FX has posted demo videos of a lot of its in-house tools on its website, including Pahi, its water simulation system, and Loki , its multiphysics framework.
The videos provide a fascinating glimpse into the toolset used by the multi-Oscar winning visual effects studio on recent movies like the Avatar sequels.
A glimpse at in-house technology of one of the world’s leading VFX studios
Although Wētā FX has won eight Academy Awards for its VFX work, it has won even more for the technology used to create those effects.
The studio has been publicly sharing details of that technology for some time now: the archive of research papers on its website goes back as far as 2007.
However, until this year, the website only included download links for PDFs of research papers: it wasn’t possible to see the tools in action.

That has now changed, with Wētā FX also sharing videos for most of its recent research.
That includes demos of a number of the key in-house tools used on its recent movies, including Avatar: The Way of Water and Avatar: Fire and Ash.
Several show Loki, the studio’s unified multiphysics simulation framework, which couples a range of simulation types, including liquids, gaseous fluids, hair and cloth.
There are also separate videos for Pahi, Wētā’s water simulation pipeline, and related research like underwater explosions and bubble simulation.
Other videos show the studio’s cloth and hair tools, plant simulation and BodyOpt, its character deformation pipeline.
