    When the Live Link Session is closed, the scene is still loaded inside Vantage but it is considered dirty and the aforementioned limitations are still in effect. A .vrscene file from the host application needs to be exported and loaded inside Chaos Vantage to enable full manipulation, editing and playback.

    UI Text Box
    typetip

    If a .vantage file is saved in an active Live Link session, it can be loaded in a next session or applied to a loaded .vrscene.
