Once you reach this point, the file is on your mobile device and no longer linked to Sketchfab. This works by providing a special link for your device to open the glTF (Android) or USDZ (iOS) file. See Managing AR embeds, below.įollowing the QR code from your mobile device camera or tapping the AR button on mobile will go directly to AR. This popup has some customization options. On desktop browsers, clicking this will open a popup with a QR code to open on mobile. Once the glTF and USDZ files are ready, anyone viewing your model will be able to click or tap on the button in the viewer to enter AR mode. When you manually change the World Scale, the model is reprocessed, but you must change the world scale by at least 5% for the change to take effect.However, that default World Scale is ignored by the initial glTF/USDZ export, and Sketchfab ensures the AR/VR object will be between 1cm and 3m in size, regardless of its measurements in meters.When a model is first processed, Sketchfab ensures the World Scale is set to something that fits the model into a 2m×2m×2m cube, regardless of its original measurements in meters.Similarly, each time you make changes to material settings or re-upload a model, the glTF and USDZ files are regenerated using the new settings. Your model scaleĮach time you change this setting and click Save Settings in the top-right corner, the glTF and USDZ file must be regenerated at that scale.

So, for example, if your models were exported in inches, you should set the World Scale to 39.37, because 39.37 inches equals 1 meter. The 'World Scale' number in 3D Settings overrides that and tells the Sketchfab viewer how many 'units' in your 3D model file are equivalent to one meter. So, if you export your 3D model measured in meters, the AR world scale should already be correct by default. Otherwise, Sketchfab's processing assumes models you upload are measured in meters. If you upload your model in FBX format, we will try to detect the scale automatically. It's best to edit 3D Settings on a desktop browser. To define the default scale of a model when it's loaded in AR, use the AR/VR 'World Scale' tools in 3D Settings. How do I change the default scale of the 3D model in AR? Turn this setting on to enable app-free AR on the model. Once you upgrade to either plan, you will find a new setting available to you in Model Properties called ' Allow AR'. How do I enable app-free AR?Īpp-free AR is currently available to Premium and Enterprise customers. Native AR relies on glTF / USDZ files generated by Sketchfab and ARCore / ARKit features of modern mobile devices (Android / iOS, respectively). Premium and Enterprise customers have access to 'native' Augmented Reality (AR) features of mobile devices, with no mobile app required.
