Unreal engine 4.22, can't get weapon glow to work in game.

[Kreiyu]

Made a weapon for Minecraft Dungeons, but i can't get the glow i'm wanting to work in game. no idea why. there is a light saber mod on the nexus that glows, but i can't really unpack and uncook the assets to look at their material files and see what they did. this is my first mod using Unreal, and detailed info on the textures and materials for MC Dungeons is sparse, so i have no idea what i'm doing wrong. 

If anyone can tell me how to get the glow working in game, and maybe an explanation of the material files that umodel unpacks, that would be awesome. weapons have two material files, but i'm not really sure what the "_storable" material difference is. 

 

Below is a screen shot of the weapon in the UE project, and in game not glowing.
