More control over Active Bodies

Create procedural animations for Active Bodies with a directable Thruster Force

Restrict Active Bodies to move or rotate along a selected horizontal or vertical axis using the Axis Lock.

Extra control over how Active Bodies interact with your scene — choose whether they should emit, attract, and retain fluids, and much more.



New and enhanced presets

Create realistic effects quickly and easily with new and enhanced presets.



Realistic Foam Patterns

Create more realistic foam, faster. Easily add variety to the size and look of your patterns.



Voxel Shader

Shade fire and smoke simulations, and meshes in a single simulator using the Voxel Shader — giving you more time to be creative.



Standalone Simulations

Speed up your simulations with the initial implementation of the Phoenix Standalone Simulator and easily debug your scenes through the Phoenix simscene Node Editor.



macOS support

Phoenix for Maya now runs on macOS.



Combined changelog since Phoenix 4.41:


NEW FLIP SOLVER New 'Size Variation' and 'Stringy' options for the Foam Pattern shapes, allowing for more diverse and interesting patterns

NEW FLIP SOLVER Multithreaded the routine where moving obstacles push the FLIP particles

NEW FIRE/SMOKE SOLVER 'Burn Smoke RGB' color option for coloring the smoke created by fuel burning

NEW ACTIVE BODIES Pick Active Bodies as emitters in Sources, as attractors in Body Force, in 'Distance To' fields in Tuner Expressions, as Birth Volumes and Render Cutters

NEW ACTIVE BODIES New Thruster node for the Active Bodies, allowing you to propel an active body in a certain direction, which can also be attached to the body so it changes direction as the body rotates

NEW ACTIVE BODIES New Axis Constraint node for the Active Bodies, allowing you to block the movement of the active body in a certain direction, or to also stop the active body from rotating around a certain axis

NEW ACTIVE BODIES New option in the Active Body Solver to use the Simulator's jammed walls as obstacles for Active Bodies

NEW ACTIVE BODIES Added an 'Affect by Foam' option to the Active Body Solver that controls how strongly the Foam pushes the Active Bodies - by default it is off

NEW ACTIVE BODIES Use Cosmos assets as Active Bodies (latest V-Ray 5 is needed)

NEW VOXEL SHADER New separate Voxel Shader node, allowing shading of both fire/smoke and meshes from the loaded data of the same Simulator without having to duplicate the Simulator

NEW PARTICLE SHADER Option to flatten particles near the Liquid Simulator's borders in Ocean Mesh mode, like the vertices of the ocean do

NEW PRT I/O PRT cache import straight into the Simulator and the Standalone Preview, without the need for a PRT Reader node. This also allows retiming of PRT sequences

NEW STANDALONE SIMULATOR New "phoenixfd" command-line executable that simulates .simscene files exported from 3ds Max, similar to V-Ray Standalone. It simulates up to 40% faster than inside 3ds Max or Maya. Currently it only supports Simulator and Source nodes, as well as Phoenix node properties. Still to be added are: Foam/Splash options, support for animated options and animated geometries, resimulation, textures

NEW STANDALONE SIMULATOR Phoenix FD menu option to Export, Simulate and simultaneously launch the Standalone Preview application to observe the simulation result

NEW STANDALONE SIMULATOR Added a Phoenix Node Viewer application for exploring the node graph of .simscene files. Dragging and dropping would also display .vrscene files

NEW STANDALONE PREVIEW Mesh Preview, including wireframe mode, customizable via the command line

NEW STANDALONE PREVIEW Viscosity Voxel Preview

NEW GPU PREVIEW Smoke Opacity modulated or replaced by textures will show in the viewport GPU Preview

NEW CACHE CONVERTER Reduce or increase grid resolution with the cache_converter tool

NEW TOOLBAR Simulation Restore button in the Phoenix toolbar

NEW PRESETS New 'Jet Engine' and 'Stormy Sea' quick setup toolbar presets

NEW PRESETS New 'Ice Cubes' and 'Speedboat' quick setup toolbar presets

NEW PHOENIX macOS support and notarized Phoenix app bundle

NEW PHOENIX Support for Maya 2023
