Easy Custom Normals is an add-on and Geometry Nodes toolkit designed for authoring custom vertex normals, specifically tailored for toon and anime-style character workflows. It features a Laplacian Smooth and Weighted Normals modifier that helps generate clean normals on uneven or triangulated topology without requiring extensive retopology.

The tool includes a rig-based Anime Face Proxy system that uses curves and Geometry Nodes to calculate controllable normals, allowing users to align the rig to a character's face and manipulate shading shapes directly via bones. The setup operates non-destructively with live previews and supports masking via vertex groups or color attributes. Once finalized, the custom normals can be applied as standard split normals while preserving shape keys, making the geometry ready for export to external game engines.
