Hi,
I’ve updated the vibration issue; it should be available for update on the FAB website in a few hours.
For the vibration to work, there are a few points to consider:
Vibration must be flagged as Default. If vibration is set to Audio-Based, it disables the conventional controller vibration.
Another point is to always call ‘UpdateOutput’ to update the controller commands, after which call the native Unreal Engine force feedback (here you don’t need ‘UpdateOutput’, as it’s already called internally by the plugin).
Below are some example images.
