Model viewer preferences

From the viewer tools, click the cog icon to view your preferences.

System resources

The model viewer by default uses the maximum available memory from your web browser for loading models. This provides the best user experience especially when working with larger complex models. If required, the resource allocation can be adjusted to a lower setting.

Showing back faces

By default the model viewer does not show the back-faces of surfaces as this allows you to navigate more smoothly around a model by not drawing surfaces that are not normally visible.

As some exporters are not consistent with how their front and back faces are shown, some parts of a model may be incomplete or missing. If this is happens, you can select Show back faces so that front and back faces are always shown. 

Note: Enabling this may reduce how quickly you can navigate around a model in the viewer.

This image shows a model in the viewer with and without Show back faces selected.
