Morph Target Animation New Jun 2026

Modern engines utilize Radial Basis Functions (RBF) and progressive blend shapes. Instead of a simple 0-to-1 linear interpolation, the engine evaluates multiple drivers simultaneously. This allows vertices to move along complex curves, enabling realistic skin sliding, muscle bulging, and anatomical pivoting without requiring joint rigs. Corrective Shape Drivers

As a morph target weight increases (e.g., a "brow furrow" shape goes from 0.0 to 1.0), the engine dynamically blends a specific normal map tile into that region of the face. morph target animation new

Old hardware could only blend positions. Modern engines blend normals & tangents too — but at a high cost. Modern engines utilize Radial Basis Functions (RBF) and
