Clothmaster is a cloth simulation add-on for Blender, built by NIXO. Its Clothify button transforms any selected object into a cloth simulation in one step: it enters edit mode, subdivides the object 10 times, adds a Subdivision Surface modifier at level 2, applies shade smooth, adds the cloth setup, and enables self-collisions.
Beyond Clothify, the add-on includes a Subdivide More button that adds further detail to a simulation, and a Pin Vertices tool that creates a vertex group from selected vertices and assigns it to the cloth modifier's pin group, which suits curtains and flags. A Collision button adds collision to an object, and a Pillow button turns any object into a pillow. A keyboard shortcut is mapped to Alt+C on Windows and Option+C on Mac.
Clothmaster targets all skill levels, from beginners unfamiliar with cloth settings to professionals. It installs through Blender's Preferences using Install from Disk with the add-on's .py file.
