This is a 3D model of the most iconic weapon of Star Wars universe : the graphlex lightsaber.

It was initially made to test eevee. Textures were all baked from procedural materials and high-poly in blender, and all materials are PBR.
The blade is made of 2 meshes, one with a volumetric shader for the foggy effect, and one with a surface shader. There are particles too. You can de/activate corresponding collections depending on your needs, so that on an average computer you can hide "Volumetric Laser blade" collection for realtime playback.
All 3 materials of the blade and particles are driven by the rig for ignition/extend effect.

It's all set up so if you play animation, you will see the loop (rotation + light up then light off) with sound effects exactly as in the demo video here.
