With Phoenix FD 3.13 we have focused on adding many frequently requested features, improving usability and support for 3ds Max 2020.
FLIP simulations are 30% faster on average and up to 2x faster on some scenes.
Now you can modify the Fire Opacity using textures in order to achieve more interesting shading results.
Save particles simulated by Phoenix FD to VDB cache files, and also import particles from other software via VDB caches
Support for 3ds Max 2020
Modulate or replace the Fire Opacity with a Texture in 'Use Own Opacity' mode
Saving of Phoenix simulated particles to OpenVDB caches
Loading of OpenVDB point data for rendering using the Particle Shader or emitting from Sources
Option to allow only expansion of the adaptive grid, but disable shrinking for the Liquid Simulator
Resimulation of the RGB channel for FLIP particles
Export of Particle Velocity for WetMap over moving geometries
Use less memory for simulation of WetMap when 'Sticky Liquid' is disabled
Grid RGB and Viscosity channels are now reconstructed from FLIP particles when using Time Bend Controls, preventing render flickering
Optimized volumetric rendering when Smoke Opacity is modulated by a texture
Motion Blur Interval Center support for the Particle Shader
Name new Particle Shaders "ParticleShader###" instead of "PHXFoam###"
Support for rendering Ocean Mesh from multiple cameras via Batch Render
Support for rendering Ocean Mesh with Stereoscopic camera
Show the force preview in the box of the loaded cache, if any, and in the simulation box otherwise
Updated OpenVDB from version 3 to version 5
Export Phoenix meshes with vertex velocity using 3ds Max 2019+'s built-in Alembic export into the 'Max_Map_Channel velocity' color set. Used for motion blur rendering with V-Ray Next update 1.1 or newer
Separate export to Alembic for the different particle systems of a Simulator by exporting the "Particles [] of []" nodes via 3ds Max's built-in exporter
Added the running Simulator's node name to the simulation viewport status
Renamed the Mapper's 'Time Constant' to 'Buildup Time'
The Phoenix FD 3ds Max plugin could not load together with V-Ray builds older than V-Ray 3.6. Restored compatibility with V-Ray 3.1
Intersecting a moving obstacle with a Solid emitter left non-emitting voxels after the obstacle
Clear Inside did not clear the volume of Non-Solid emitters in Surface Force mode in the Fire/Smoke Simulator
Empty adaptive grid expanded by itself when Extra Margin was used and Expand and Don't Shrink was On
Crash with 'Simulate Air Effects' and forces affecting the 'Air' system of a Liquid Simulator, since Phoenix FD 3.04
WetMap was not equally generated over flat surfaces and might not appear on horizontal or vertical surfaces
Subsiding liquid at the front of a long moving ocean container with Motion Inertia
Fixed various issues with moving ocean containers producing disturbances and waves at their borders
Trying to resimulate over a liquid cache with no Liquid particles showed different messages the first and second time
Simulation restore did not go back to the last backup frame and could cause a crash, since Phoenix FD 3.12
Voxelization of a large amount of small bodies used excessive amounts of memory, since Phoenix FD 3.11
Voxelization of hundreds of geometries with very small sizes was slower on many threads compared to simulating on 1 thread
Geometry with Initial Liquid Fill which was also selected in a Source in Volume Brush or Volume Inject mode created double amount of liquid particles and this caused explosions
Particles with small size used as emitters for Liquid had random Discharge strength
Sources did not emit from Thinking Particles when simulating through Deadline or Backburner
Flickering FLIP liquid mesh near emitters when Input Play Speed was below 1
When two or more Simulators had any overlapping walls, volumetrics weren't rendered correctly with V-Ray GPU
Crash with instanced Simulators in Volumetric Render Mode during sequence render with V-Ray GPU [requires V-Ray Next update 1.1 or newer]
Crash when rendering a scene containing any Particle Shaders with V-Ray GPU
Crash when rendering a scene containing a VolumeGrid and a Simulator with V-Ray GPU
Shading volumes using only textures still required a loaded cache file with V-Ray GPU
Volumes loaded from OpenVDB caches that contain internal rotation rendered clipped with V-Ray GPU
Fire Lights kept illuminating the scene after the cache sequence ended during sequence render
Crash when rendering a volume with Create Lights intersecting a geometry with a Light Material
Using many chained texture maps in the volumetric shader produced different renders of the same frame when rendering repeatedly
Volumetric Light Cache still consumed additional memory even when it should have been disabled in Progressive V-Ray rendering
Memory leak when rendering with GI and any V-Ray render elements
Particle Shader particles appeared smaller when exported and rendered from a VRScene
Crash when rendering a Particle Shader without a linked Liquid Simulator, since Phoenix FD 3.12
Slowdown of Particle Shader Bubble/Splash/Cellular rendering with linked Liquid Simulator and 'Use Light Cache', introduced in Phoenix FD 3.04
Slowdown the second time you rendered a large amount of Foam particles
Ocean Mesh used excessive amounts of memory when rendered with Spherical Panorama camera
Ocean Mesh was not built correctly when the viewport was set to Orthographic mode
Crash when rendering Ocean mesh with Cutter Geom and Motion Blur

Crash during fire/smoke simulation if using a Grid Texture reading the Temperature of the same Simulator in a Mapper affecting Temperature with 'Initializer' Off
Crash when rendering a scene with Grid Texture used as a mask in a Blend material with Motion Blur
