I only get that behavior in our own project, unfortunately. Well, mostly. We’re on 4.27.
If I use the VR template I get mostly consistent results. However, if I mess with the haptic curves I can get close behavior to what I’m seeing. The first vibration is normal, and then subsequent ones are very faint. In our project they’re non-existent though, so it’s not quite the same.
I’ve exhausted everything I can try, and UE5 isn’t stable enough for our project to use. I guess we’re just haptic-less while UE5 matures.
