About Mustard Simplify

Mustard Simplify is a Blender add-on that disables certain scene and object features that impact viewport performance with a single click. Clicking Simplify Scene automatically disables heavy features, which helps maintain high FPS during animation and when working with dense static scenes. The operation is non‑destructive: no mesh edits are made and all original settings are preserved, with modifier visibility and shape‑key states restored when Simplify is turned off. Users can select which modifier types and shape‑key groups to disable, and define an Exceptions list for objects or collections to remain untouched. Additional utilities include a Scene Complexity Analyzer that colors meshes as a heatmap, an Armature Proxy Generator, and a Data Removal tool for unused data blocks. Version 2026.2.0 introduced the heatmap analyzer and preset simplify settings. Compatibility requires Blender 4.3 or newer.
