A groundbreaking solution designed for realistic and breathtaking fire, smoke and explosion effects

This unique plug-in is a powerful gaseous fluid dynamics simulator created by Sitni Sati for seamless integration with Autodesk Media & Entertainment’s Maya™ modeling and animation software. Designed for use by visual effects artists, game developers, and visualization professionals who demand the utmost in realism, FumeFX is unrivalled in its ability to capture the nuance and complexity of fluid gas behavior.


FumeFX 4 offers many new features that help simulations to run faster and with more detail.

The new FumeFX 4 QCG solver is up to twice as fast as the CG solver found in FumeFX 3.0. Along with other simulation optimizations, FumeFX 4 can complete simulation faster than any previous version of FumeFX.

New vorticity type has additional control over vortices which helps user to fine tune the final result. The highly optimized Spline Follow force field allows various special effects that were impossible before.

Built-in Black-body radiation shader and new burning model that includes Oxygen are powerful tools for achieving realistic fire and explosion animations. Sharpening at render-time will bring out maximum possible detail from your existing caches. Fully multithreaded cache pre-processing at render time will result in significant time savings across the render farm.

Features such as faster solver, advanced vorticity, new burning model, smoke and fire sharpening at render time, fields sharpening at simulation time, improved caches handling and many other will allow users to create more detailed simulations in less time.

Effectors are the most valuable and the most powerful feature. With just a few mouse clicks, artists can tweak the laws of physics or alter any simulated field based on built-in rules. For example, Effectors can drive setups where vorticity is controlled by velocity, gravity is controlled by smoke color and fire is created in voxels where velocity is above a user-defined threshold. All of this can be further refined by powerful test conditions or even confined to the Effector's gizmo.

RenderWarps are another great tool that will find application on many VFX shots. This feature allows users to apply space warps such as FFD, Bend, Taper and Noise to precomputed FumeFX caches. As RenderWarps are a post-process, re-simulation is not needed.

N-Sim enables artists to connect many grids together and execute their simulations simultaneously as one big simulation. This approach can be invaluable for increasing the level of detail in scene setups such as a rocket launch.

The GPU accelerated Preview Window is another time-saver, providing instant feedback for adjusting rendering parameters. Self-shadows are computed extremely fast and the user can orbit the camera around FumeFX with self-shadows in real-time(1). FumeFX also supports preview with geometry included in simulation.

FumeFX has been production proven in titles such as Hugo, Ghost Rider: Spirit of Vengeance,Thor, Priest, 2012, Skyline, Suckerpunch, Spiderman 3, X-Men Origins: Wolverine, Superman Returns, Iron Man, The Host (Gwoemul) and various games cinematics such as Warhammer Online, Classic Transformers, Dante's Inferno and others.

Key Features

The innovative FumeFX user interface combines all the major fluid simulation components making the simulation setup easy and efficient. It allows user to change parameters during the simulation with instant feedback or even to directly edit FumeFX sources without the need to switch back and forth between dialogs

The FumeFX interface integrates simulation, rendering, preview, presets and source parameters in one place. It provides quick and easy navigation through simulation caches and offers intuitive control of simulation parameters.

GPU Preview
The GPU preview produces render-comparable images to give instant feedback on appearance and behavior of the simulation. Among many advantages, it supports creation of the preview animation during the simulation.

In order to boost productivity, FumeFX can utilize BackBurner, Deadline, or remote desktop applications to run simulation tasks on another computer with FumeFX or FumeFX SL installed.
