Mesh Smoother - Mesh Edge Normal Editor, Mesh Modifier

Mesh Smoother is a Unity asset for selectively smoothing edges on your meshes. It features an easy-to-use interface with no coding required. It uses a non-destructive workflow where smoothed meshes can be stored as files (.asset or .obj) while keeping all animations, blend shapes, and other data intact. It provides precise edge normal recalculation for a convenient subset of edges without introducing new geometry. Full source code is included. It supports Unity 2021.3+, 2022, Unity 6, Unity 6.3, and LTS versions. Usage: select your model, open the Mesh Smoother tool, pick the edges, and click Smooth.
