Hello there,
I tried using the water system of Unreal 4 on a VR project, everything looks great. I used a simple landscape, but when I play it in VR mode it looks like some areas are cut and it bugs the view on the VR headset.
Viewport:
VR Mode:
Any thoughts of what this could be?
Have same problem, and I don’t find any information how to fix this.
Have searched all google already.
Have any luck maybe to find solution ?
BUT if you disable VR “Instanced Stereo” under project settings.
It works, but probably very ‘‘costly on FPS’’ .
Please EPIC GAME fix water on Virtual Reality 
You need my game on your engine 
This issue is known and being addressed for 5.0. Disabling instanced stereo can work as a temporary solution to your project, especially if you’re not draw call bound.
For me turning on mobile HDR worked just fine
Confirming, 5.4.4 crashes if adding WaterBody to the map.
