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 'Size Variation' and 'Stringy' options for the Foam Pattern shapes, allowing for more diverse and interesting patterns
Multithreaded the routine where moving obstacles push the FLIP particles
'Burn Smoke RGB' color option for coloring the smoke created by fuel burning
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 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 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 option in the Active Body Solver to use the Simulator's jammed walls as obstacles for 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
Use Cosmos assets as Active Bodies (latest V-Ray 5 is needed)
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
Option to flatten particles near the Liquid Simulator's borders in Ocean Mesh mode, like the vertices of the ocean do
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 "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
Phoenix FD menu option to Export, Simulate and simultaneously launch the Standalone Preview application to observe the simulation result
Added a Phoenix Node Viewer application for exploring the node graph of .simscene files. Dragging and dropping would also display .vrscene files
Mesh Preview, including wireframe mode, customizable via the command line
Viscosity Voxel Preview
Smoke Opacity modulated or replaced by textures will show in the viewport GPU Preview
Reduce or increase grid resolution with the cache_converter tool
