This is Darth Vader's Lightsaber. This model does not include the blade. If you want to make your own blade in blender create a cylinder and put an emission material on it. I have included the PBR materials just in case it does not automatically plug them in. From testing the metal material just needs to have the roughness map plugged in as Unreal could not accomplish that on its own. I have tested this model in Unreal Engine 4 and can confirm that the model loads in and works. This project contains 2 assets from CC0Textures.com, licensed under CC0 1.0 Universal.
