Animations and triggers are not yet supported in the new DeepAR Studio Beta. These features are currently in development and should be released within the current year. Alternatively, we support the `Emotions` node component, which will trigger the blend shapes with names corresponding to the detected emotions: _sadness_, _surprise_, _happiness_, _neutral_ and _anger_. ---

Do you have a crash or does the effect just not change in the preview?
