Release History
7.6
Released on 05.August.2026
New Features and Improvements
- FumeFX: Added a new Multigrid PCG solver (CPU and GPU) for up to 2x the GPU simulation speed compared to PCG and overall 10x faster than CPU simulation with FumeFX 5.
- FumeFX: Added a post load Fast Upres algorithm that adds detail to cached simulations on load, without re-simulating. CPU and GPU supported.
- FumeFX: Added a post load Retimer algorithm that changes the playback speed of cached simulations on load, without re-caching. CPU and GPU supported.
- FumeFX: Added a memory cache that keeps loaded frames in RAM, so Upres, Retime and Sharpen stay interactive during playback and scrubbing.

- NodeWorks: Added Ocean Spectrum texture that reads NodeWorks Spectrum data file and use it for geometry displacement - VRayDisplacementMod in Vector displ Object mode support or as a bump map.
- NodeWorks: Added Ocean Spectra Mix texture.
- NodeWorks: Ocean Spectrum node can now export its spectrum parameters to a text file, but can also read and apply any spectra from the file.

- NodeWorks: Ocean Foam and Bubbles can now be created by any other source and affected directly by NodeWorks forces.
- NodeWorks: Ocean added Submerged Decay option - bubbles now fade out of the surface's waves/forces/flow with depth and re-couple as they rise, for realistic underwater-to-surface motion.

- NodeWorks: Memory Cache optimizations and substantial speedup of over 2x.
- NodeWorks: Instanced shape display now uses the 3ds Max 2023+ viewport instancing API, for much faster display.
- NodeWorks: Texmap slots now support drag-and-drop from 3ds Max Material Editor texmap slots onto NodeWorks texmap buttons.
- NodeWorks: Added a Preferences option to highlight changed parameters.
- NodeWorks: Extrude and Face Shatter nodes added U and V tiling options for side faces.
- NodeWorks: Vertex Color node removed the Write To Shape option and added a channel option instead.
- NodeWorks: Display Pin Value node now supports memory cache and a range of particle inputs.
- NodeWorks: Improved listbox UI controls (used in Object Params, Object Properties, etc.).
- NodeWorks: Gradient Ramp and Color Ramp UI can now float outside the NodeWorks window.
- NodeWorks: Spinner edit controls now accept the Tab key to confirm a typed value and move to the next field.
- NodeWorks: Tabs added option to invert tab states.
- NodeWorks: Comment node added option for user defined background color.
- NodeWorks: Object Properties node now lists all available 3ds Max object properties to choose from.
- NodeWorks: Regex filtering across the board now also supports specifying layers.

- NodeWorks: Gravity node added a per-particle variation percentage.
- NodeWorks: Gen Surface node exposed pins for its Slope filtering options.
- NodeWorks: Surface Gen node's Random Uniform option is now significantly faster.
- NodeWorks: Changing a Display node's gradient no longer triggers a resimulation.
- NodeWorks: Arnold Curves node no longer restarts the simulation when changing radius scale and similar display-only parameters.
