I have an issue where I need to turn off assets, audio and GUI when a specific marker is currently being tracked by the camera. Whilst vice versa when it is no longer being tracked. The main problem is that I can't find a way to get hold of something I can use as a trigger to do so.
Is there any script I can use to either recognise a specific marker when it is tracked by the ARCamera?
Is there anyway to track the video playing with the video prefab from video playback unity package?
