Hello,

FumeFX 7.5 GPU has been released today.


With the FumeFX 7.5 update, artists gain NVIDIA® CUDA acceleration that delivers, on average, 2× to 5× faster simulation performance compared to CPU-based workflows. 
FumeFX GPU simulations also avoid typical GPU memory limitations—if available GPU memory is exceeded, the simulation automatically falls back to CPU mode. This allows even the most complex, memory-intensive simulations to complete reliably without interruption. 
While many sparse fluid solvers struggle to preserve convincing detail and motion, FumeFX GPU maintains the visual richness and behavior artists expect, combining high performance with high-end visual quality. 
In addition, FumeFX 7.5 introduces true two-way interaction between fluids and scene objects. Objects influence the fluid flow, while the fluid simultaneously applies forces back onto the objects, affecting their motion and behavior. 
Built on NodeWorks’ fully node-based framework and integrated PhysX rigid-body simulation, this two-way coupling enables physically consistent and predictable results.

Hi. I'm a retired hobbyist new to FumeFX. For a good few years now, I have been working with 3dS Max (currently with version 2026) and VRay7, with some ZBrush and Blender input as well. I am looking forward to the challenge of learning about Fume FX 7 and incorporating its effects into my scenes. It would be much appreciated if someone could kindly point me in the direction of some instructional videos suitable for newbies to FumeFX.

TIA

Hello,

FumeFX 7.1 update has been released today.

This update brings a major performance and workflow update focused on viewport performance, cache handling, and interoperability with external tools like Houdini, Maya Bifrost, Embergen and Liquigen.

The new RenderWarps algorithm has been completely rewritten and optimized for standard 3ds Max modifiers such as Bend, Twist, Taper, Skew, and Stretch.
This implementation delivers much sharper and more detailed deformations while running approximately five times faster than the previous version.
The system is hybrid by design—retaining the original sampling-based algorithm for complex deformers like FFD—ensuring both compatibility and speed where it matters.

Viewport visualization has been refined with color-coded grids and grid name labels that match each FumeFX object’s assigned color.
These colors are also shown in the floating FumeFX dialog, allowing users to immediately identify which dialog corresponds to which simulation grid.
The new display options also include cached color preview in the Voxel Data Display and a “Hide Grid” toggle available in both display modes.

OpenVDB import has been extended with Y-Up support and automatic detection of available channels when loading third-party caches such as Houdini or Embergen, streamlining the setup process and removing the need for manual channel assignments.
Cache output path handling has also been improved, allowing users to define custom separators and control the number of frame digits in file names.

The NodeWorks system introduces a new lightweight Alembic export path for particle and mesh caches.
The updated Save Cache and Particle Export nodes can now export point clouds and particle shapes directly to Alembic format, producing minimal cache files that load seamlessly into Houdini and Bifrost with matching attribute data.
The Load Caches node and PartLoad tool now support Alembic point cloud import with an optional Y-Up axis conversion and path variable resolution.

Additional updates include improved viewport performance in PartLoad with support for per-particle color display, new extrusion modes in the Extrude node (along vertex normals or custom vectors), enhanced MaterialID control, and a visual alert system that highlights NodeWorks dialog errors in red.
FumeFX Wind has also gained an animatable “Active” parameter, making it easy to enable or disable wind influence over time.

Altogether, FumeFX 7.1 refines simulation and workflow efficiency across both the FumeFX core and NodeWorks ecosystem, strengthening its integration within 3ds Max and external pipelines.

Sitni Sati releases FumeFX 7 which introduces NodeWorks Ocean, a physically accurate, GPU-accelerated ocean simulation system built natively for 3ds Max. It brings real-time ocean generation, adaptive meshing, secondary particle effects, and dynamic object interaction into a unified workflow designed for both VFX professionals and visualization artists.
With the addition of the Ocean Sim node, users can generate cinematic water surfaces driven by spectrum-based wave models, blend multiple wave types with Perlin noise, and eliminate visible repetition through tile variation and height masking. 
The Foam & Spray node enables real-time generation of foam, bubbles, and spray, rendered efficiently as Arnold points or volumes with full support for Arnold User Data. For object interaction, the Ocean Dynamics node provides true two-way coupling between scene objects and the water surface, including buoyancy, wakes, and secondary particle emission.

I have a question.
I want to use ISurf but it's not working.
1: Simulate with FumeFX
2: Create ISurf and select FumeFX
3: Mesh is not displayed. Adjusting the threshold didn't help.
(Max2023, FumEFX6.5.4)
Thank you in advance.

I don't know how to use FumeFX's GPU Liquids with Spline Follow

Are there any helpful tutorials?

Hello,

hi 
im using fumefx 6
in pflow when add fumefx follow node and add fume fx grid 
when play 3dsmax crashes!

I thought FumeFX would possibly be compatible but it just never shows up at all in the menus. So I am assuming i will have to downgrade to a earlier version of C4D for Fume to even be registered? IF there is a way to get it to run with the last build please let me know I just barely got the key so I havent tried everything but I just wanted to ask first before I started tinkering.  Thanks in advance
