In 5.7, the a.EnableQueuedAnimEventsOnServer=1 is already on by default, but I was still having the issue. Turns out you can set anim notifies on the base animation asset, or on the anim montage asset. Once I transferred the notifies over to the montage, everything now works as expected. It seems that any notifies on the base anim assets aren’t taken into account by the listen server when using montages to play those animations in multiplayer.
