Stable Releases

The next stable release (1.0.5) will coincide with the official stable release of Blender 2.80 planned for July 2019. Until the release of Blender 2.80, try out the Experimental Releases for the latest features and improvements!

  • version 1.0.4a (Aug 24 2018)
    • Fixed bug that would cause holes (missing triangles) in the surface mesh (issue #372)
    • Fixed bug that would cause missing chunks near the boundary of the surface mesh (issue #376)
    • Fixed bug that would cause banding artifacts in the surface mesh (issue #377)
    • Fixed bug where using world scaling would cause incorrect distribution of generated whitewater particles (issue #373)
  • version 1.0.4 (Aug 09 2018)
    • Added support for baking from the command line (issue #329) - See Notes
    • Added debug functionality to visualize the true domain bounds (issue #299)
    • Added functionality to restrict viewport/render fluid display from the 'FLIP Fluid' physics button (issue #222)
    • Added Inflow option to constrain fluid inside of an inflow object to match the inflow emission velocity. Allows inflow to work when submerged (issue #322). Allows low velocity emission values to have the effect of slowing down inflow emission (issue #90) - See Notes
    • Added volumetric water shader 'Water (volumetric)' courtesy of Grant Wilk of Remington Graphics

    • Fixed UI issue to disable ability to insert keyframes into 'Hold Frame' option (issue #340)
    • Removed 'Invert Surface-Contact Normals' option in 'FLIP Fluid Surface' settings. This option does not work as intended and is not useful.
    • Fixed bug where whitewater particles would be killed when boundary behaviour was set to 'Ballistic' (issue #354)
    • Fixed bug where changes to whitewater particle scale would not be reloaded in the viewport (issue #339)

    • Added operator to preferences menu to check for version updates (issue #314)
    • Added support for fluid surface motion blur rendering (issue #87) - See Notes

    • Added functionality to invert fluid surface-obstacle interface normals
    • Fixed bug where stats could stop being processed (issue #280)
    • Improved fluid particle stability

Experimental Releases

Experimental releases will give you access to the latest updates and features, but these builds may contain bugs and lack documentation. Please let us know what you think of the experimental builds or notice any problems, we love to hear your feedback!

The features and improvements in the experimental releases will be included in the next stable release. The next stable release (1.0.5) will coincide with the official stable release of Blender 2.80 planned for July 2019.

  • version 9.0.5.5 (May 17 2019)
    • Try it out! This version is considered stable and 'production ready' as long as you are using Blender 2.79. See Blender 2.80 known issues.
