Solo game developer Rod3dArt managed to port their fun cartoonish "tire feet" effect from Blender, where they made and animated it, to Unreal Engine and let everyone interested see the result.
In essence, it's a "rig racing through an animated curve," as the creator described it, and it looks great on the little cannon-head character in the demonstration. Rod3dArt is planning to make a Steam page for their Cuphead-inspired game soon, and we'll see this effect and the character there, so stay tuned.
