Vertices move in straight lines between shapes, which can cause organic tissue (like eyelids or lips) to look unnatural or collapse during transitions.
Specific versions of that same mesh where vertices have been moved to form a new shape (e.g., a "smile" or a "blink"). morph target animation new
With recent updates to Unreal Engine 5, Nanite (virtualized geometry) now natively supports programmable rasterization, including morph targets and splintering deformations. This means film-quality meshes with millions of polygons can utilize morph targets directly in real time without traditional level-of-detail (LOD) degradation. Vertices move in straight lines between shapes, which
