Planar Reflections lag behind VR headset movement
Reporting that reflection captures lag because they happen before late update is applied.
Includes an experimental patch that fixes the issue, but perhaps not in the right way.
1. Create a new VR template
2. Add a planar reflection plane and enable 'Global Clip Plane'
3. Create a shiny material, ensure that "Planar Reflections" is checked under "Forward" in the material settings, and add it to the scene aligned with the the planar reflection plane
4. You may also need to set Reflections->Reflection Method to "None" under project settings, or Lumen may overwrite the reflection
5. Check to see that the planar reflection renders properly in VR, and does not show any "lag" behind headset movement
Bear in mind that the planar reflection will not appear perfectly accurate unless the surface using it is perfectly aligned with the reflection plane itself.
