Toon Outline Tool lets you fix broken toon outlines by writing smoothed normals into Vertex Color (RGB) for both Static Meshes and Skeletal Meshes.
Use the stored direction in your materials/PP to get clean, continuous contours and silky light falloffs on hard edges, UV seams, and dense LODs—without changing topology or skinning.
