Lava simulation processes and data in Blender

Building Extension

To build the extension you first have to download the dependency wheels:

Windows

Double click on get_wheels.cmd

Linux/Mac

sh get_wheels.sh

Then you can run this command to build the addon zip file:

blender --command extension build --split-platform

See below if you don't have Blender available in your CLI.

Adding Blender to CLI

Prerequisites

• Download and install Blender from the official website

Windows

1. During Blender installation, check the option to "Add Blender to system PATH"
2. If you missed this option or need to add it manually:
   • Find your Blender installation directory (typically C:\Program Files\Blender Foundation\Blender X.X)
   • Open Start menu and search for "Edit environment variables"
   • Click on "Environment Variables"
   • Under "System variables", find and select "Path", then click "Edit"
   • Click "New" and add your Blender installation directory
   • Click "OK" on all dialog boxes

macOS

sudo ln -s /Applications/Blender.app/Contents/MacOS/Blender /usr/local/bin/blender

You may experience Python environment clashes, this also works;

/Applications/Blender.app/Contents/MacOS/Blender --command extension build --split-platform

Linux

If you installed Blender via package manager, the CLI should already be available.

If using a downloaded version, add Blender to your PATH:

export PATH=$PATH:/path/to/blender

Add this line to your .bashrc or .zshrc file to make it permanent.

Verify Installation

Test that Blender CLI is working by opening a terminal/command prompt and typing:

blender --version

This should display the installed Blender version.
