Autodesk 3ds Max 2018.3 Released – Fluids

One of the top 3 requested 3ds Max Ideas site items is now complete with the addition of Bifröst Fluids which was previously only available for Maya.

Read an overview of 3ds Max 2018.3 at the Autodesk’s AREA blog.


  • Fluids allow you to create fluid simulations directly inside 3ds Max using Bifrost technology.
  • Read/create BIF files for direct interoperability with Maya.
  • Save/create presets based on viscosity, giving the illusion of different fluid types (honey, water, jelly, etc.).
  • Read/open VDB files.
  • Dynamically create meshes based on the simulation, which can be processed at the same time or independently.
  • Outputs mesh to Alembic so you can play anywhere Alembic is supported or have faster playback.

Motion Field

  • The Motion Field space warp works with Fluids, 3ds Max's particle systems, and deforms meshes.
  • Combines multiple forces that would have had to be done separately previously, such as drag, wind, and gravity.
  • Ability to turn specific components on/off as needed.
