VIDEO TUTORIAL: How to make a 3D Model optimized for Augmented Reality with AR Code?
Tutorials | 03/07/2025 |
Dive into the captivating realm of Augmented Reality (AR) with our guide on integrating digital content into real-world settings. Preparing 3D models for optimal AR application can be a challenge, but our in-depth guide offers insights on using Blender, a free 3D modeling software, for AR readiness.
Centering Your 3D Model for Perfect Augmented Reality Display
Properly center your 3D model within the scene to ensure an ideal AR visualization. An off-center model might appear distant. Center it easily through the following steps:
- Import your 3D model into Blender.
- Choose your model and set its origin to its geometry, ensuring accuracy.
- Place your model at the coordinates (0,0,0).
- Save your 3D model for AR applications.
Improving AR Performance: Compress Your 3D Model Files
Boost your AR experience by minimizing your texture image file sizes. To optimize loading speed, follow these simple steps:
- Import your model into Blender.
- Export using the .gltf + .bin + textures format.
- Open textures in GIMP, a free image editor.
- Resize images to 1024x1024 or smaller, saving as .jpg files with 90 or lower resolution.
- Replace textures in Blender or adjust the .gltf file to modify texture formats.
- Save the newly updated file.
Vertex Reduction for 3D Model Optimization
Enhance loading times by reducing the complexity of your 3D model through vertex reduction. Here's how:
- Import your 3D model into Blender.
- Opt for a mesh to decimate and target under 50,000 faces, retaining visual quality.
- If no moving parts are involved, decimate multiple meshes simultaneously by joining them.
- Export in .glb format, selecting “Apply modifiers” but not “Compress”.
- Upload the optimized model to AR Code.
Exporting in Preferred 3D File Formats for Augmented Reality
For an uninterrupted Augmented Reality experience, ensure your 3D model is exported in the proper format.
When uploading 3D files to AR Code, use automatic uploads for .GLB, .USDZ, .PLY, .STL, .FBX, .OBJ, .X3D, .GLTF, or .ZIP. For formats like .DAE and .ABC, seek specialized support.
Keep your files under 25MB to guarantee swift loading and seamless experiences.
Scale Your 3D Model for Seamless AR Integration
With reduced textures and complexity, upload your model to AR Code ensuring it measures under 25MB for a smooth AR display, avoiding slowdowns from large, high-definition models.
Verify and adjust your model's scale during uploads to AR Code. For resizing in Blender:
- Choose your model and press S (“scale”).
- Size accordingly, move your cursor to set and click to confirm.
- Export the model in .glb format with the correct scale.
Conclusion: Achieving Balance for Augmented Reality Success
Balancing visual quality and performance in 3D models for AR is crucial for quick loading and flawless display across devices. By optimizing textures and reducing complexity, you deliver compelling and effective AR experiences.

Frequently Asked Questions
Why is centering my 3D model so important?
Centering ensures the best positioning in AR views. Misalignment might make the model appear distant. Use Blender to set the origin to its geometry and place it at (0,0,0).
How can I effectively reduce the file size of my 3D model?
Decrease file sizes by reducing texture sizes and simplifying model complexity. Export in .gltf format, scale down textures, and convert to .jpg files to lower size. Simplify by decimating meshes below 50,000 faces.
Which file format is best for AR Code uploads?
Use formats like .GLB, .USDZ, .PLY, .STL, .FBX, .OBJ, .X3D, .GLTF, and .ZIP for AR Code uploads. Seek help for other formats such as .DAE and .ABC.
What is the optimal file size for AR 3D models?
3D models should be kept under 25MB for optimal user experience. Larger files can delay loading, negatively impacting AR experiences, despite the clearer definition they may provide.
