Troubleshooting procedure
If the error "Indoor Maps: missing" is displayed, generate the map within NavVis IVION.
Drag down the list to refresh the Site List View or close the site list view and re-open it:
Go back to instance view and select the instance again.
If there are no other loadable sites on any instance, close the app and re-open it.
If there is a loadable site available: go to that site and then navigate back.
FAQ
My maps are not loading in the site model
If maps are not loading in NavVis IVION, first verify that the SiteModel entity (Floor) includes the correct floor and point cloud for which maps need to be generated. If you made adjustments to the SiteModel, regenerate the maps. Note that the map generator works best in indoor environments without significant slopes — areas with slopes or ramps may result in only partial map generation. For detailed steps, see the troubleshooting procedure in this article.
