Simplicage is a Blender add-on designed to generate physics-ready cages for 3D models using Blender's native cloth physics. It provides tools to quickly create simulation cages and collision boxes directly from existing meshes, bone selections, or vertex groups. The toolset includes a preset system for common physics applications and a dedicated management panel for organizing, binding, and baking the resulting cages. It utilizes a triangle-based remesher and an advanced weight transfer algorithm to automatically bind clothing to the generated cages.
