One‑Click Fixes is a comprehensive Blender addon designed to streamline and automate the most common geometry, UV, rigging, simulation, and scene‑management tasks. With over 100 one‑click operators organized into intuitive panels, you can resolve mesh errors, optimize UV layouts, clean up rigs, bake animations, manage materials, set up lighting, and much more—all without memorizing complex menus or hotkeys.

Key Features

Geometry Fixes & Cleanup

• Merge Loose Vertices & Remove Doubles: Instantly weld stray verts within a custom threshold.

• Recalculate & Fix Flipped Normals: Ensure all normals are consistent and correct inside/outside orientation.

• Triangulate & Convert to Quads: Switch between tris and quads to suit your pipeline.

• Select & Delete Loose/Non‑Manifold Parts: Highlight problematic geometry for manual inspection or auto‑remove.

• Decimate, Subdivide & Smooth: Control polycounts and surface smoothness with a single click.

• Auto‑Smooth, Flip Faces & Check Ngons: Preview and correct shading and face topology issues.

UV & Unwrapping Tools

• Smart UV Project & Angle‑Based/Conformal Unwrap: Fast, quality unwraps with minimal manually placed seams.

• Cube/Cylinder/Sphere & Lightmap Projection: Generate UVs optimized for each primitive shape.

• Pack Islands, Average Island Scale & Optimize Layout: Maximize UV space usage and ensure consistent texel density.

• Align & Merge UV Seams: Clean up and perfect your UV seams before baking or texturing.

Rigging & Animation Helpers

• Normalize Vertex Weights & Generate Automatic Weights: Balance skinning weights or auto‑assign based on bone proximity.

• Auto‑Rename Bones, Reset Pose Transforms & Clean Bone Hierarchy: Keep armatures organized and restore bind‑pose transforms.

• Bake Animation & Simplify Keyframes: Convert procedural motion to keyframes and reduce f‑curve complexity.

• Fix Zero‑Weight Vertices & Bone Orientation: Catch unassigned verts and align bone rolls with world axes.

Material & Scene Management

• Remove Unused Materials & Optimize Slots: Clean material slots and combine similar shaders.

• Separate/Combine by Material: Group or merge mesh parts based on material assignments.

• Group Objects, Batch Rename & Create Backups: Organize, label, and safeguard your scenes!

• Add HDRI Lighting & Set Active Camera: Quickly set up environment lighting and switch cameras without digging through menus.

• Purge Orphan Data & Optimize Scene: Remove unused datablocks, images, textures, and materials to reduce .blend size.

Simulation & Special Tools

• Add & Bake Smoke/Fire, Fluid (Water) & Particle‑Based Fire: One‑click setup for complex fluid and gas simulations with default domain and emitter settings.

• Generate Collision Mesh & LOD Chains: Auto‑decimate a low‑poly collision mesh or generate multiple LOD levels.

• Mirror Mesh, Align to Active & Visual Transform: Snap and mirror geometry or bake visual transforms for consistent exports.

Workflow Boosters

• Run All Fixes: Apply all major geometry cleanup and rig‑prep steps in one operator.

• Object Statistics: View vertex, edge, face, bone, and group counts at a glance.
