Just tested the “Instanced Stereo” VR setting under Rendering project settings exporting to Android (ES2 → development) and I see the following build failed error message:

known issue? This was testing with a totally blank new project with just a few spheres in it.

Hello ,

I was able to reproduce this issue on our end. I have written up a report (UE-25738) and I have submitted it to the developers for further consideration. I will provide updates with any pertinent information as it becomes available. Thank you for your information and time.

Make it a great day

Instanced sterero is not supposed to work on Android. A fix has been checked in to indicate this in the tooltip and to force it off during packaging if on for unsupported platforms. At the moment on D3D SM5 and PS4 support this.
