Game Asset Optimizer
Asset Optimizer is a comprehensive toolkit for optimizing 3D assets for Unity and Unreal Engine. Streamline your workflow with one-click batch optimization presets, automated LOD generation, dual UV unwrapping (texture + lightmap), smart mesh decimation, and CAD model cleanup.
Key Features: • Batch Optimization Presets - CAD Import, Game Asset, VR Optimized, Custom • LOD Generation - Automatic hierarchy with 2-8 levels for Unity/Unreal • Dual UV System - UV0 for textures, UV1 for lightmaps • Smart Decimation - Multiple algorithms with quality preservation • Vertex Merging - Essential for CAD models with duplicate vertices • Multi-Object Support - Process entire scenes at once
Perfect for game developers, VR creators, and anyone working with CAD imports. Supports Unity LOD Groups and Unreal Engine LOD naming conventions out of the box.
What's New
1.0.2 November 21st, 2025
Changes in this release:
- Renamed extension from "VR Asset Optimizer" to "Game Asset Optimizer" to avoid confusion with Blender's Asset Browser system.
- Added context safety checks - All operators now include poll() methods to ensure they only run in Object mode, preventing potential errors.
- Updated UI consistency - All panel labels and categories now reflect the "Game Asset" branding.
- Removed Import-Export tag - Corrected categorization to focus on Modeling, Mesh, and Pipeline workflows.
- Improved operator reliability - Replaced high-level operators with lower-level API calls where appropriate for better stability.
What it does: Complete optimization toolkit for game engines (Unity/Unreal), featuring mesh decimation, LOD generation, dual UV unwrapping, vertex merging, and batch optimization presets.
Requirements: Blender 4.2.0 or later
Very handy, thank you!
