I finally got it to work, thanks. And just in case anyone else is as clueless as me… When I unzipped the files into the addon folder, I guess there are two layers of folders: …\Blender Foundation\Blender\2.78\scripts\addons*Blender_UE4_VectorFieldEditor-master\FGA_VectorFields*. It would not recogonize it that way. By copying the ‘FGA_VectorFields’ folder to the ‘addons’ folder, it pulled it right up: …\Blender Foundation\Blender\2.78\scripts\addons*FGA_VectorFields* works just fine. Thanks again, I’m having fun with it.
