Screen Space Reflection and Ambient Occlusion doesn't work at all

Hi Friends,

I have a weird issue SSR doesn’t show at all in my current project.


There is no reflection of the water tap in the mirror.
My previous VR project which has been migrated from 4.26 still works fine. but this project I created from 4.27 VR template has this issue.
The project is built for Windows platform and DirectX 11 because I have a crash issue with DirectX 12.
SSR settings in PostProcessVolume take no effect too.
Ambient Occlusion also doesn’t work no matter I try.
What could be wrong with my project and how can I fix it ?
Thanks.

I have just found another topic about the same issue. it seems like Epic Game has disabled the SSR and AO in VR Template for real.
Someone said that AO and SSR won’t work correctly in VR. But my previous project works pretty well with them both in VR. I don’t remember exactly how did I get them both to work because it is quite a long time ago. But maybe I did start with a normal template and then migrate the VR Character and stuff into it somehow.
Is there any better way to get SSR and AO back in the current VR template please?
