Can be tested out in the QAGame project. I’ve tested this in Editor. Besides the erratic behavior already logged in [UE-33361](https://issues.unrealengine.com/issue/UE-33361), SetHapticsByValue stops vibrating after 3-4 seconds. Works as expected, i.e. continuous Vibration, on the Vive Controllers. ---

Still not working in 4.15. On the Vive it works fine. ---

Still not working in 4.17.2 ---

I wonder if [this question](https://answers.unrealengine.com/questions/1025599/successive-haptic-pulses-stop-working-after-a-few.html) might be related. I wasn’t sure, given that I encoutered this with the Valve Index controller, but perhaps as a work-around you could try calling SetHapticsByValue without any 0 amplitude calls following it. ---

Don’t know the cause, but found a simple workaround (UE 4.26). Touch controller will stop vibrating after 3 or so seconds only if the amplitude stays the same. This can be easily prevented pulsating your amplitude a bit (not noticeable to user) **Make Pulsating Value** does the job. ![338517-pulsehapticsamplitude.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/d/5/7/d57987403f2814a95ed08471365006e57247a850.png) **IF you’re using OpenXR plugin** , every SetHapticsByValue needs to be preceded by another SetHapticsByValue with frequency and amplitude set to 0. The amplitude being the same does not matter. ![338516-openxrhaptics.png](https://d3kjluh73b9h9o.cloudfront.net/original/4X/1/b/1/1b1e8200f868d7a927995bb103d7b1460446ce4e.png) ---

Interesting that your work-around is to precede every call with a setHapticsByValue of 0, whereas mine was to find a way around a frequency of 0 being sent AFTER. (worth noting) I haven’t had a chance to try your suggestion yet. ---

huh, weird 😛 Well, OpenXR really messes with VR stuff in 4.26.
