Tidy Monkey: Your Swiss Army Knife for Blender Workflow Optimization (Free)

Ever spent hours cleaning up boolean artifacts, fixing normals and repositioning origins? The free Tidy Monkey add-on brings three essential toolsets to fix common issues especially if your artwork is for a game engine such as Unity, Unreal or Godot.
Group Scene Organization
- Align objects and space them apart equally on any axis
- Smart mesh selection tools for finding similar objects based on verts count and partial object name
- One-click origin point management, i.e. center, snap to bottom or any face
- Checker edge selection for topology optimization ### Handy Cleanup Operations
- “Beautify” automatically orienting normals towards the average direction, triangles-to-quads conversion, removes loose topology and unnecessary vertices, copies neighboring normals from the parent object for seamless shading between two separate objects, creates and adds modifier stacks.
- Fix object rotation to match normals of the selected face
- Removal of unused textures and materials
- Batch bone and vertex group renaming to get rid of that mixamo: prefix without breaking the animation
- Quick action generation with the correct names from animation strips
Effortless Exports
- One click FBX and GLB export with automatic texture packing
- Removal of unused materials during export
- Automated action generation for animations
