This tool allows you to edit, import and export the FGA file format used for vector fields in Unreal Engine 4's particle systems.

The editor works by creating a volume with a sorted particle system that can be influenced by most forces available in Blender. The particle system can also be used with a smoke domain to simulate smoke flow, but can currently not be influenced by fluid simulations using a fluid domain.

The velocities of the particles in the volume are read using different methods in the Velocity Type dropdown and blended with the currently saved velocity values using different methods in the Blend Method dropdown.
