  • Phoenix FD 3.05 for 3ds Max and Maya

    Hey everyone,

    Today we are releasing a new version of Phoenix for both 3ds Max and Maya. It contains many fixes and here are the important improvements and new features as well:
    - Support for Maya 2018;
    - Up to 30% faster simulation compared to 3.04 and 3.00.01;
    - New Force Preview which you can use to check how Phoenix as well as native Max and Maya forces will affect the simulation;
    - New method for slowing down fire/smoke simulations without resimulation (check the example videos here: https://docs.chaosgroup.com/display/...Input-FrmBlend );
    - Resimulation of Phoenix VDB caches and load and restore from Phoenix VDB caches.;
    - Stronger Approximate Scattering for brighter regions and lower scattering for the darker regions of the same volume;
    - [Maya only] Support for nParticles as source emitters and nParticles with isntanced shapes as emitters and obstacles.
    - Support for 3ds Max modifiers on FollowPath splines;
    - A new command line cache_converter tool for converting already existing AUR cache sequences to OpenVDB without simulating again;
    - Reworked entirely the C++ SDK.

    Important bug fixes in this version are:
    - [3ds Max only] Fixed crashes when simulating using any Phoenix textures in 3ds Max 2018 Update 2 and Update 3;
    - Fixed issues with time-bend resimulation present in 3.04;
    - Liquid particles penetrated the walls of thin static or moving geometries in large numbers. This has largely improved, but still needs some more work;
    - Fixed fire/smoke simulation instabilities with huge veliocities coming in through open walls;
    - Fire/smoke simulations with Buffered or PCG conservation may produce different results on each run;
    - Many fixes for the FLIP solver simulation.
    - Fixes for issues with the Ocean Horizon rendering present in 3.04.

    You can check the 3ds Max builds here:

    I have aur cache from build 3.04.03 Build 1711037811.
    Do I need to remake the sim or reconstruct the container with 3.05?
    Thanks!

      Hey,

      No need to do that. Do you have any issues with an older scene?

      Cheers!

        I found an issue...maybe...
        Running my ship-on-the-ocean project.
        I had run the previous sim thinking I did not need to export particles, and did not have the liquid channel turned on, this to conserve hard drive space.
        Now with the new version installed, I attempted to re-simulate splash and foam on aur cache from the previous version, got a message in the log that the Liquid Particle channel is missing. Must enable it in the output panel and simulate again before resimulating.
        I will relaunch the sim with the new version, but I may have waited on upgrading the farm to the new version had I known...

        Edit> Frame zero aur cache file size with the liquid particle export turned on, increased from 22mb to 164mb. Frame 1 aur cache file size is up from 11mb to 186mb.
        I am going to try again from beginning with new sim.

          Indeed, this is expected - you need the liquid particles in order to do a resim, and the position channel for a large number of particles takes quite a lot of space.
