VIDEO TUTORIAL: How to make a 3D Model optimized for Augmented Reality with AR Code?
Tutorials | 07/06/2025 |
Explore the fascinating world of Augmented Reality (AR) as we bring digital content into the real world. Preparing 3D models for AR can be challenging, but this post provides a comprehensive guide to readying your models using Blender, a free 3D modeling tool.
Center Your 3D Model in the 3D Scene for Optimal AR Display
Ensure that your 3D model is perfectly centered in your scene for an ideal AR view. If it's off-center, the model might appear distant in AR. Centering it is easy:
- Import your model into Blender.
- Select your model and set its origin to its geometry, ensuring the center is accurate.
- Position your model at coordinates (0,0,0).
- Save your 3D model for AR.
Enhance AR Performance: Reduce Your 3D Model File Size with Textures
Enhance loading speed by reducing the texture image file sizes of your 3D model. Here’s a quick guide to help:
- Import your 3D model into Blender.
- Export in .gltf + .bin + textures format.
- Open texture files in GIMP, a free image editor.
- Resize images to 1024x1024 or smaller and save them as .jpg files with a resolution of 90 or lower.
- Replace textures in Blender or edit your .gltf file to change texture formats.
- Save the updated file.
Optimize Your 3D Model with Vertex Reduction
Further improve loading speed by minimizing your model’s complexity through vertex reduction. Follow these steps:
- Import your 3D model into Blender.
- Select a mesh to decimate and aim for fewer than 50,000 faces while maintaining visual integrity.
- For models without moving parts, decimate multiple meshes simultaneously by joining them first.
- Export in .glb format with "Apply modifiers" selected, but avoid "Compress".
- Upload your optimized model to AR Code.
Export Your Model in Preferred 3D File Formats for AR
For seamless Augmented Reality experiences, export your 3D model in the correct format.
When uploading your 3D files on AR Code, utilize automatic uploads for .GLB, .USDZ, .PLY, .STL, .FBX, .OBJ, .X3D, .GLTF, or .ZIP. For other formats like .DAE, .ABC, .IFC, .STEP, .IGES, .3DM, .BREP, and .JT, seek dedicated support.
For optimal user experiences, keep your 3D files under 25MB to avoid loading delays.
Scale Your 3D Model for Effective AR Integration
With compressed textures and reduced complexity, upload your model to AR Code. Ensure the model is no larger than 25MB for smooth AR display and avoid potential slowdowns of larger, high-definition models.
Check and adjust your model’s scale when uploading to AR Code. For resizing within Blender:
- Select your model and press S (for "scale").
- Adjust size by moving your cursor and click to confirm.
- Export the appropriately scaled model in .glb format.
Conclusion: Balance Quality and Performance for AR Success
Optimizing 3D models for AR requires a balance of visual quality and performance to ensure quick loading and flawless display across devices. By reducing textures and complexity, you can provide engaging and efficient AR experiences.

Frequently Asked Questions
Why is it crucial to center my 3D model?
Centering your 3D model ensures optimal positioning in AR views. Misalignment can lead to displays that make the model seem distant. Use Blender to set the origin to its geometry and position it at (0,0,0).
How can I efficiently reduce my 3D model’s file size?
Reduce file sizes by minimizing texture file sizes and simplifying model complexity. Export in .gltf format, resize textures, and turn them into .jpg files to decrease size. Simplify by decimating meshes to fewer than 50,000 faces.
Which file format is optimal for AR Code uploads?
Utilize formats like .GLB, .USDZ, .PLY, .STL, .FBX, .OBJ, .X3D, .GLTF, and .ZIP when uploading to AR Code. Seek assistance for other formats such as .DAE, .ABC, .IFC, .STEP, and similar.
What is the ideal file size for AR 3D models?
Keep your 3D models under 25MB for the best user experience. Bigger files can delay loading times, affecting the AR experience negatively, despite any enhanced definitions larger models may offer.
