This 3D model of "The Graphlex" from Star Wars was made for testing eevee viewport in Blender. It comes as in the cover video, with the looping animation and a rig in order to animate it. The blade is made of a volumetric shader and/or a solid geometry (I added particles too). You can deactivate collections depending on your needs for better performances. For instance, without the volumetric shader it's realtime in eevee viewport. All 3 materials are "rigged" with drivers for ignition/extend effect. You will find CC0 soundtrack made with CC0 samples from freesound.org and one CC0 hdri from hdrihaven.com packed in the blend file.
