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,

FumeFX 6.7.2 update has been released.
The Voxel Data Display system has been fully rewritten, delivering over 10× faster viewport performance for smoother, more responsive interaction. New opacity mode enables channel-based transparency, helping users better visualize key simulation details.

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

Hello,

FumeFX 6.7.1 is now available. 
Over the past two years, we've released 19 updates, introducing 190 new features and improvements along with 150 bug fixes. 
We’re excited to continue bringing new and innovative features in future updates.

New Features and Improvements
- FumeFX: FumeFX Arnold/Redshift Shader now has the capability to blur caches.  Use negative sharpen value to apply blur. 
- NodeWorks: Surface Gen now has the output texmap color pin which is available when using Texmap as a filter. 
- NodeWorks: Rendering particles as Arnold Points now support multiple materials based on the particle MtlID attribute.
- NodeWorks: Added support for 3ds Max 2026. 
- NodeWorks/FumeFX: Added support for Arnold 7.4 and MaxtoA 5.8.1.0 for 3ds Max 2024 to 2026.
 
Fixes
- FumeFX: Arnold RenderView did not update when Arnold/RS sharpen/blur parameters changed. 
- NodeWorks: Resolved a viewport performance issue where the display of millions of particles was significantly slower compared to PBD liquid particles or foam.
- NodeWorks: Instanced geometry was rendered despite the particle or particle group having the "Render as Point" flag.

FumeFX 6.7 has been released with many new and exciting features.

NodeWorks now features built-in C# scripting, allowing users to extend FumeFX and NodeWorks with custom logic and automation. The integrated script editor supports syntax highlighting, auto-completion, function call tips, and error bookmarks, making script development faster and more efficient. Users can also reference external scripts and assemblies, enabling modular and reusable code structures. With support for C# parallel loops, the system allows full multithreading, significantly improving performance in complex, computation-heavy tasks compared to traditional node-based setups. The FumeFX 6.7 update also brings major performance boosts. 

The Spline Force node is now fully GPU-based for PBD Liquids, resulting in up to 45 times faster execution compared to CPU processing. 
Additionally, GPU support for voxel grid calculations delivers a 10x speed increase. 
Particle Custom Channels have also been optimized, achieving over 20% faster performance for smoother, more responsive simulations.

Hello,

Today, FumeFX 6.5.4 update has been released with new important functionality related features. Here is a short list of important updates:

- FumeFX Particle Source object now includes an option for user-defined particle lifespan. This new option provides significant help for artists using tyFlow, as it lacks the particle lifespan information required for proper AFC controls operation.
- NodeWorks added a 3ds max particle interface option, allowing users to select particle groups and PBD liquid particles for integration with third-party plugins like tyFlow.
- NodeWorks added a new Propagate node, enabling particle attributes, including custom attributes, to propagate from nearby particles.
- NodeWorks Spline Force node added a Spline Lock option to ensure particles follow the first spline curve they are assigned to. Without this, particles may switch splines based on proximity.
- NodeWorks Spline Force node added a Spline Index input pin, allowing procedural spline selection for each particle. These additions greatly enhance the node's flexibility.
