3D Artist Mizzauro has just released Shape Key Smoother, an alternative to Blender’s native features. This tool enables you to quickly create smooth shape keys by allowing you to rough out a shape key and then smooth it selectively using the surrounding area.
Unlike Blender’s built-in Smooth operator in Edit mode or the Smooth brush in Sculpt mode, which often distort volume and shape, this method maintains them intact.
If your existing shape keys have become overly smoothed, Shape Key Smoother can help you restore lost detail with ease. Compatible with Blender 4.1 and later, it’s suitable for both stylized and realistic projects, whether working on characters or any shape key-driven system.
