Screenshot of the circle tech from Blender. We don't have access to animations so instead, the circles use a texture panning material to make the texture go around. The edges were also extruded slightly so it's still visible from a parallel view.
A mod for Monster Hunter: World that I created based on a weapon known as the Curel Oath from Nier: Automata. Simple and elegant!
