VIDEO TUTORIAL: How to make a 3D Model optimized for Augmented Reality with AR Code?
Tutorials | 04/08/2025 |
Explore the exciting world of Augmented Reality (AR) and learn how to integrate digital content effortlessly into real-world environments. Preparing 3D models for AR applications may seem daunting, but our comprehensive guide simplifies the process using Blender, the free 3D modeling software, to prepare your models for AR.
Centering Your 3D Model for Perfect Augmented Reality Display
Ensure your 3D model is perfectly centered in the scene for an optimal AR experience. An off-center model may appear misplaced. Easily center your model with these steps:
- Import your 3D model into Blender.
- Select your model and set the origin to its geometry for precision.
- Position your model at coordinates (0,0,0).
- Save your 3D model, ready for AR usage.
Improving AR Performance: Compress Your 3D Model Files
Enhance your AR experience by reducing the size of your texture image files. Optimize loading times with these steps:
- Import your model into Blender.
- Export the model using .gltf + .bin + textures format.
- In GIMP, a free image editor, open and resize textures to 1024x1024 or smaller, saving as .jpg with 90 or lower resolution.
- Replace textures in Blender or modify the .gltf file for texture changes.
- Save the updated model.
Vertex Reduction for 3D Model Optimization
Improve loading times by simplifying your 3D model with vertex reduction:
- Import your 3D model into Blender.
- Select a mesh to decimate, aiming for models under 50,000 faces while preserving visual integrity.
- For non-moving parts, decimate multiple meshes by joining them.
- Export in .glb format, select “Apply modifiers” without “Compress”.
- Upload the optimized model to AR Code.
Exporting in Preferred 3D File Formats for Augmented Reality
Ensure a seamless AR experience by exporting your 3D model in suitable formats.
While uploading 3D files to AR Code, utilize automatic uploads for formats like .GLB, .USDZ, .PLY, .STL, .FBX, .OBJ, .X3D, .GLTF, or .ZIP. Specialized support is available for .DAE and .ABC.
Keep individual files under 25MB to assure quick loading and smooth experiences.
Scale Your 3D Model for Seamless AR Integration
With reduced textures and complexity, upload your model to AR Code ensuring it remains under 25MB for an efficient AR display, preventing slowdowns from large models.
Check and adjust your model's scale when uploading to AR Code. To resize in Blender:
- Select your model and press S (“scale”).
- Adjust the size and confirm by clicking.
- Export the model in .glb format with the appropriate scale.
Conclusion: Achieving Balance for Augmented Reality Success
Balancing visual quality and performance in 3D models is key for quick loading and flawless AR display across devices. By optimizing textures and reducing complexity, you offer engaging AR experiences.

Frequently Asked Questions
Why is centering my 3D model so important?
Centering ensures optimal positioning in AR views; misalignment could make the model appear distant. Utilize 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?
Minimize file sizes by reducing texture dimensions and simplifying model complexity. Export using .gltf format, scale down textures, and convert to .jpg files. Simplify by decimating meshes to less than 50,000 faces.
Which file format is best for AR Code uploads?
Optimal formats for AR Code uploads include .GLB, .USDZ, .PLY, .STL, .FBX, .OBJ, .X3D, .GLTF, and .ZIP. Seek assistance for other formats like .DAE and .ABC.
What is the optimal file size for AR 3D models?
Aim to keep 3D models under 25MB for the best user experience. Larger files may cause delays, impacting AR performance despite providing higher definition.
