Heavy Blade / Unreal Engine Sketch
Animation turned into a sequence and exported to Blender for Mesh Creation

Slashes made using a curve and profile, which are converted to a mesh and then duplicated and flipped to provide a front and back-facing coaster

Objects fractured in a 3D-Voronoi pattern and then animated. Animation is baked to Shape Keys, and then baked out into Vertex Animation Textures
