Overview of FumeFX 7.5.2

FumeFX 7.5.2 is a multiphysics simulation plugin designed to integrate seamlessly into the 3ds Max 2022–2026 production pipeline. Unlike basic particle systems, FumeFX simulates the physical properties of fluids — including temperature, velocity, fuel, and density — within a voxel-based grid. This scientific approach produces highly detailed, interactive effects that respond dynamically to scene geometry, forces, and animation.

The plugin is widely adopted in film and game production for its ability to deliver cinematic-quality fire, smoke, and explosion effects. It has become a cornerstone tool for blockbuster VFX and AAA game cinematics, trusted for combining physical accuracy with an efficient, artist-friendly workflow.

With version 7.5.2, Sitni Sati continues to refine the GPU solver, NodeWorks node-based system, and rendering integrations, ensuring FumeFX remains at the forefront of fluid simulation technology for 3ds Max users.

Key Features of FumeFX 7.5.2

FumeFX 7.5.2 includes a comprehensive set of features designed to streamline complex VFX creation:

Voxel-Based Fluid Solver

The core simulation engine uses a high-fidelity voxel grid to calculate fluid dynamics based on temperature, fuel, and smoke density, ensuring physically accurate motion and interaction. This approach supports millions of voxels within the viewport, enabling detailed simulations that hold up under close inspection.

GPU Acceleration with NVIDIA CUDA

FumeFX 7.5 introduced powerful NVIDIA® CUDA acceleration, delivering on average 2× to 5× faster simulation performance compared to CPU-based workflows. The GPU solver is particularly effective for high-resolution fire and smoke simulations, and it automatically falls back to CPU mode if GPU memory is exceeded, preventing workflow interruptions.

NodeWorks Node-Based Workflow

NodeWorks is a node-based editor that provides unparalleled control over simulations. Artists can create complex, layered effects by chaining together nodes for sources, forces, and modifiers, enabling non-destructive experimentation. NodeWorks includes over 170 nodes covering particles, cloth, soft body, rigid body dynamics, and fluid components.

Multiphysics Support

Beyond fire and smoke, FumeFX supports simulation of liquids, splashes, foam, and rigid body interactions, enabling the creation of rich, complex scenes where different material types collide and interact.

Advanced Rendering Integration

FumeFX offers direct rendering support for Arnold CPU, Redshift, V-Ray, and Corona, ensuring volumetric elements render with accurate light interaction, shadows, and translucency. Native OpenVDB support allows seamless import of volumetric caches from tools like SideFX Houdini and EmberGen.

GPU Viewport and Interactive Feedback

The redesigned GPU viewport in FumeFX 7.5 delivers a new multiview core with significantly faster feedback, supporting proper blending with scene geometry and direct viewport PNG export during simulation.

Two-Way Coupling

FumeFX 7.5 added two-way coupling between fluids and rigid bodies, allowing simulations to actively interact with objects — pushing, lifting, and reacting to motion for realistic physical behavior.

What’s New in FumeFX 7.5.2

The 7.5.2 update, released on February 24, 2026, focuses on workflow improvements, viewport enhancements, and NodeWorks refinements:

Enhanced GPU Viewport Display

The Arnold/Redshift Volume Shader viewport display now uses color when the color channel is enabled, providing more accurate visual feedback during simulation. This improvement helps artists make better creative decisions without waiting for final renders.

FumeFX Wind Radial Falloff

FumeFX Wind gained radial falloff support, along with a refined UI layout. This feature allows for more natural, localized wind effects that taper off smoothly rather than affecting the entire simulation grid uniformly.

NodeWorks Single Frame Mode

NodeWorks simulation now includes a Single Frame mode for fast per-frame tuning. This mode enables artists to iterate quickly on specific frames without re-simulating the entire sequence.

tyFlow to FumeFX Quick Preset

A new Quick Preset for tyFlow to FumeFX makes it faster and easier to drive FumeFX simulations directly from tyFlow particles. The preset automates channel setup, reducing the manual configuration required for tyFlow-driven simulations.

Additional NodeWorks Enhancements

• Drag-and-drop support for particle groups directly into the node editor

• Import Particle System node with a Setup NodeWorks Channels button for tyFlow custom channels

• Spawn Gen node options for spawning from particle shape surfaces

• Import Shape node options for tracking position, rotation, and scale

• Object Info node output pin for object bounding box size
