Please add info about Vector Fields tool for Blender into the UE4's documentation

Currently there is a working tool for Blender to generate and export Vector Fields from Blender into UE4: GitHub - isathar/Blender_UE4_VectorFieldEditor: Blender addon that adds support for working with 3D vector fields using the FGA file format.

However, UE4 docs only mention Maya.

Epic, please add the info and link to the official documentation for UE4.
