Seamless GLB Exporting and Optimization

GLB Optimizer is a powerful Blender add-on designed to streamline the export and optimization of your 3D models into high-quality, web-ready GLB files. Perfect for game developers, VR/AR creators, and web designers, GLB Optimizer ensures your models are efficient, lightweight, and optimized for real-time applications.

Key Features:

• Texture Optimization: Adjust format and size for lightweight textures.
• Mesh Simplification: Minimize polygons and maintain essential details.
• Hierarchy Flattening: Lower draw calls for enhanced performance.
• Advanced Compression Options: Choose between Draco and Meshopt for size reduction and runtime efficiency.
• One-Click Optimization: Quickly generate GLB files that load faster and run smoother.

Install Add-on

The add-on can be installed as an extension or as a legacy add-on in Blender versions older than 4.2.

Install Node.js and glTF-Transform

To use advanced glb/gltf optimization, we need to install an external library called glTF-Transform. It offers a lot of sophistiated functions to improve file size and performance.

Export and Optimize

To export your model the Blender file needs to be saved first. Then change the settings to your liking and press export. With the glTF-Transform enabled, you now have the options to choose the texture compression, texture size and compression method along with some scene tools to flatten hierarchy, join all meshes that don't have animations or even reduce the polycount by simplifying the mesh.

Advanced GLB Exporting

Export entire scenes or selected objects with customizable settings.
Include or exclude lights, animations, and apply modifiers during export.
Save GLB files directly to your project directory for easy management.

Preview Directly in Web Browser

Includes a built-in web preview to view optimized GLB files directly in your web browser. Quickly ensure your models look and perform as expected before deployment.

Multiple Compression Methods

Choose from Draco, Meshopt, Quantize, or disable compression to suit your project's needs.
Optimize both geometry and animations to balance quality and performance.

Flexible Texture Optimization

Select from various texture formats: WEBP, KTX2, AVIF, or allow the add-on to automatically determine the best format.
Scale textures in real-time within Blender and see the quality directly on your model before exporting.
Adjust texture sizes to reduce file weight without compromising visual fidelity.

Benefits

Enhanced Performance: Significantly reduce GLB file sizes for faster load times in web applications and games while maintaining high visual quality.
Streamlined Workflow: Save time with automated export and optimization processes, and easily manage settings across multiple projects.
Improved Compatibility: Ensure your GLB files are compatible with major web platforms and real-time engines, optimizing models for various applications without manual intervention.
GLB Optimizer simplifies the complex process of exporting and optimizing 3D models, allowing you to focus on creating stunning visuals. Whether preparing assets for a game, virtual reality experience, or an interactive website, GLB Optimizer provides the tools you need to deliver professional-quality models with ease.

Requirements:

Blender 4.2 or later
glTF-Transform installed for optimization features
Optional: KTX-Software for KTX2 texture compression
