Working with 3D models – Tourguide

What 3D model formats to use?

At the moment we support GLB files. This is a 3D model format in which all textures are bundled in a single file. Furthermore, it has many advanced animation and lighting features. For GLTF files we provide a conversion tool.

There is no hard limit to the complexity of a 3D models, but:

We recommend to keep the number of vertices below 30.000. Easier is to look at the filesize of the model, generally models below 30MB tend to load well.

It is always useful to check your specific models in the app, as there are many different factors impacting performance and visual looks.

Where can I get high quality 3D models?

To purchase existing high quality 3D models, you can use the following websites: https://sketchfab.com/, https://www.cgtrader.com/, or https://www.turbosquid.com/.

How can I create my own 3D models?

Create models using 3D software like Blender.

Scan objects using 3D scanning software such as Polycam or RealityScan, which can be use to convert camera images to a 3D model. The quality of the results is mostly determined by the capabilities of the device used.

Troubleshooting

My 3D model looks different than expected

Sometimes a 3D model can look different in AR studio than in your 3D software. This can include:

My 3D model is darker than expected

Some textures show up transparent

When creating materials for your 3D models, make sure that either back face culling is turned off, or that the alpha mode is not set to alpha blended.
