Download – Build 4.41.00


With the Phoenix FD 4.41 hotfix we added support for the GPU preview and velocity streamline preview for 3ds Max 2022.

We also added the ability for the FLIP liquid Adaptive Grid to expand based on a combination of particle channels, instead of using only the liquid particles like before.

The Property Lister now supports animations for the Phoenix node properties, has multiple selection and the ability to create properties for multiple nodes at once, and also has a number of other useful improvements and fixes.

We did a number of fixes for the simulation and cache handling, also allowing you to mesh huge simulation grids, and we fixed various issues on machines with many cores.



  Expand the Liquid Adaptive Grid based on a combination of several particle systems


  Enabled the GPU Preview for 3ds Max 2022

  Animation support for the Property Lister and right click menu for manipulating keys

  Shift+click multiple selection, create node properties for multiple nodes at once, frozen top row of the table

  Re-enabled the Velocity Streamline preview

  More verbosity for 3dsmaxbatch.exe simulations

  Allow animating of the Make Body Static, Mass, Density and Apply Gravity and Buoyancy per-node properties

  Drag particles are not supported by the FLIP solver, so hidden them from the Liquid Source


  Phoenix GUI license was taken with 3dsmaxbatch.exe simulations in 3ds Max 2019 and newer

  Resimulation that used Cooling and Amp. Resolution cooled off differently than the base sim

  IDs of liquid particles created using Initial Fill Up or Initial Liquid Fill were different each time a new simulation was started

  Liquid particles could overshoot moving geometries pushing them and cross their walls even with many Steps per Frame

  Splash could be born By Free Fly in air pockets under the liquid surface

  Crashes when meshing grids or smoothing mesher nearing or over 2 billion voxels

  Crash when resimulating liquids to VDB, since Phoenix 4.10

  Crash when constructing the scalar Speed channel of VDBs whose bounding box does not start at 0,0,0

  The cache appeared skewed when the selected viewport was first turned into the Extended GPU Preview Window

  Starting or restoring the simulation sometimes randomly failed on Threadripper 3990X

  Pressing Esc/Shift+Esc did not always stop the simulation
