• Where do the data options in the GUI come from?

The list of data options that show up in the GUI are based on the *.json and *.csv files that are inside Assets/StreamingAssets/DxRData/ directory. To specify your custom url enter the url manually in the specs, e.g., via a text/code editor.

• Where do the mark options in the GUI come from?

The list of mark options that show up in the GUI are based on the folders that are inside Assets/DxR/Resources/Marks directory. Each folder contains a game object prefab which is used as a prefab for visual marks. During deployment, DXR instead checks the list of marks in Assets/DxR/Resources/Marks/marks.json - this allows customizing the list of usable marks at deployment.

• Why are the buttons in the GUI not responding to my tap interactions via the HoloLens?

If the GUI buttons are not working during debugging, try reapplying the default mixed reality settings again: Mixed Reality Toolkit -> Configure -> Apply Mixed Reality Scene Settings. If you have this issue in a deployed version, try the following: 1) In InputManager object, set the UI Raycast Camera parameter to MixedRealityCamera, 2) Click DxRGUI component under DXRVis prefab and under Canvas in Inspector window, uncheck Receive Events, 3) set the Camera to MixedRealityCamera, 4) Recheck Receive Events option.

• Can I change the names of game objects under the DXRVis prefab?

You can change the name of the DXRVis game object instance in your scene as you like. However, do not rename any of the game objects within the DXRVis hierarchy unless you know what you are doing because in most cases, scripts use the object names to search for them at runtime.

• Why is my specified interaction not showing up?

When specifying interactions, make sure there is only one interaction for each data field. Only the first one is created.

• How do I fix an IOException: Sharing violation ... error?
