When using VisionLib with Unity, make sure you’ve copied a valid license file into the StreamingAssets/VisionLib/
folder. Also check the name of the file: if it is not named “license.xml”, drag and drop it in the public field of the TrackingConfiguration
component on the VLTracking
GameObject.
If you still encounter problems, send us an email at request@visionlib.com and attach your license file. We’ll check, if something is wrong with your file.
