6. The tool will appear in the Sidebar (N-panel) under the "LS - Pro LOD Tool" tab

2. Generating LODs

Select Your Model

Select the rigged character or static mesh you want to optimize.

Configure LOD Levels

• Check the LOD levels (LOD0-LOD7) you wish to create
• Choose between Ratio Mode (e.g., 0.50 for 50%) or Target Mode (specific polygon count)
• Select your Decimation Style: Balanced, Aggressive, or Quality

Rigging Settings

• Use Single Armature: When enabled, all LODs share the same skeleton and stack at origin for perfect alignment
• Ideal for game engines that handle LOD switching automatically

Mesh Optimization

• Preserve Symmetry: Choose your axis (X, Y, or Z) to maintain mirrored topology
• Preserve Custom Normals: Keep your specific shading data intact
• Preserve UV Seams: Protect UV boundaries during decimation
• Vertex Group Protection: Paint weight 1.0 on vertices you want to protect from reduction
• Limit Weights: Set Max Bones (default 4) for mobile and standard game engine compatibility

Tip: Click "Generate LODs" to create organized LOD collections. The original mesh will be hidden automatically.

3. Exporting to Game Engines

Naming Convention

Select your target engine from the dropdown:

• Unreal Engine - Applies _LOD0, _LOD1, etc. suffixes
• Unity - Uses Unity-compatible naming
• Custom - Define your own suffixes for Godot, CryEngine, or other engines

Export Settings

• Export Target: Choose FBX (Unreal/Unity) or GLB (Godot/Web)
• Export All LODs in Single File: Bundles all LOD levels into one FBX/GLB (recommended for Unreal auto-LOD detection)

Note: Click "Export LODs" and select your destination folder to save your game-ready files.

4. LOD Preview System

• ◄ Prev / Next ►: Cycle through LOD levels in viewport
• Quick Buttons (0-7): Instantly view any specific LOD level
• Show All: Display all LOD meshes simultaneously

5. Utilities

• Select LODs: Quickly selects all generated LOD objects in the viewport
• Show Original: Reveals your original high-poly model
• Delete All LOD Groups: Cleans up the scene by removing all generated LOD data and collections
