FumeFX 7.5.5 Update: V-Ray Support and NodeWorks Upgrades

POSTED 5th OF May, 2026, Posted by Summer Magdaraog

FumeFX 7.5.5 introduces a focused set of updates across simulation performance, procedural tool expansion in NodeWorks, rendering pipeline integration, and stability improvements. This release is centered on improving GPU efficiency, expanding algorithmic simulation workflows, and strengthening compatibility with modern V-Ray and Arnold pipelines.

Performance and Core System Updates

FumeFX continues to improve GPU-based workflows with this release:

GPU viewport display during simulation is now 10–20% faster
CUDA updated to 12.9.1 (requires NVIDIA driver ≥ 528.33)

These updates improve responsiveness during simulation playback and interaction, especially in complex or high-density scenes.

NodeWorks: Expanded Procedural Simulation System

NodeWorks received a significant upgrade in 7.5.5, with new tools focused on procedural motion, growth systems, and data-driven particle behavior.

New “Algorithmic” Node Group

A new category called Algorithmic introduces motion and structure-based simulation tools:

Shortest Path
Fork
Swarm
Space Colonize

These nodes are designed for procedural behaviors such as:

pathfinding and guided motion
natural growth simulation
swarm and crowd-like behavior
branching and structural generation

Shortest Path Node

The new Shortest Path node enables particles to move through a field toward target particles using the most efficient route available.

Key capabilities include:

tunable turn penalties for motion shaping
per-waypoint cost control
Catmull-Rom smoothing for refined trajectories

This makes it suitable for controlled motion design and procedural navigation systems.

Space Colonize Node

The Space Colonize node implements a classic space colonization algorithm for procedural growth.

It generates organic structures such as:

trees and branching vegetation
root systems
vein-like formations
lightning-style patterns

Growth is driven by attractor points, allowing highly art-directable organic structures.

Fork Node

The Fork node simplifies branching generation with controls for:

branch count
angle variation
spacing and distance

It is designed for frost patterns, dendritic structures, and procedural splitting systems.

Random Weighted Node

Improves procedural randomness by introducing weighted distribution control, allowing more natural variation in particle systems and procedural setups.

Life Node

Adds direct control over particle lifespan, improving simulation control and behavioral timing.

Spline and Surface Workflow Improvements

Several updates improve spline-based and surface-based workflows:

Spline Test Node: returns closest position, tangent, and curvature
Spline Gen Node: now outputs tangent and additional data
Spline Follow Node: supports start behavior options and outputs position, tangent, curvature
Spline to Shape Node: now supports spline knot rotation data

Surface Generation Improvements

Surface Gen gains more flexible emission options:

polygon-based emission modes
random and uniform distribution options
inverted selection support
initial speed now defaults to zero for predictable behavior

Particle Emission and Grid Enhancements

Spawn Gen Node Updates

new cluster modes (Trail / Segment)
emission based on particle travel distance
segment-based spawning using two-point definitions

Grid and Simulation Tools

Advect Node can now remove particles outside grid bounds
Write Voxel auto-enables channels when connected
Grid Sources auto-manages channel activation
Display Grid supports point data visualization with caching and velocity scaling
Display Attributes adds custom color and gradient ramp support

Rendering and Pipeline Integration

V-Ray Support

FumeFX 7.5.5 introduces improved V-Ray compatibility:

Particle custom channels are now supported in V-Ray shaders
Requires V-Ray 7.30.02 or higher

This improves integration for production rendering workflows, especially in FX-heavy scenes.

Arnold Support

Full UVW channel support added for meshes in NodeWorks

This strengthens interoperability in Arnold-based pipelines.

ISurf and Ocean System Updates

ISurf Improvements

particle color channel support (FumeFX and particle data)
velocity channel support
particle size control option
unified viewport display modes:

None
Color
UVW
Velocity
Mask

Ocean System

motion vector generation added for surface and foam particles

AfterBurn Integration

AfterBurn is now included in the FumeFX package with several updates:

rewritten viewport display system (spheres, box, cylinder)
stability improvements for light handling
crash fixes when deleted lights are referenced

FFX Vertex Write Improvements

memory caching added for faster timeline scrubbing
UVW data clamping (min/max controls)

Fixes and Stability Improvements

This release includes several important fixes across simulation and NodeWorks:

FumeFX

fixed GPU vortex falloff issue
fixed crash when burning with oxygen

NodeWorks

fixed Spawn node crash when position input is connected
fixed FFX Vertex Write hang on scene load
fixed particle import update issues for deleted particles
fixed PDB Source rotation handling
fixed voxel writing issues during cache load
fixed spline-to-particle connection issues under memory caching
fixed spline-to-shape update issues when changing shape types

What This Update Delivers

FumeFX 7.5.5 is a refinement and expansion release focused on three key areas:

faster GPU-based simulation performance
expanded procedural systems in NodeWorks
deeper integration with V-Ray and Arnold pipelines

For artists working in FX, motion design, and architectural visualization, this update strengthens both control and flexibility across simulation and rendering workflows.
