Lightwave 11.6 python script for converting Blender particle cache files to a Lightwave particle pfx file.

right click the link above to download

To install copy the file to the python script's plugin folder, something like:

"C:\Program Files\NewTek\LightWave11.6\support\plugins\scripts\Python\"

blender particles panel

Read in sections and Number of particles in section are used to read particle simulations that do not fit in memory. It reads all the bphys files to get each particles frame range then reads through them again to get the motion data.


  1. Create a particle simulation inside Blender
  2. Save the .blend scene file to activate the Disk Cache
  3. Twirl open the cache section and choose the Disk Cache checkbox
  4. Run the simulation and a collection of bphys files will be created at the same location as the blend file
  5. Add Dynamics folder: Edit > Paths Options..., Paths, Create Directories.
  6. Use this script to convert to Lightwaves pfx file format
  7. Add an emitter to the lightwave scene and load the pfx file into it

  • The Blender Bake button will create an extra file that contains timing information. This extra file is not created when the simulation is created from the timeline.
  • Information on the Blender point cache can be found here, especially useful are the comments at the bottom of the page ,
