I am using the post processing version 2.1.0 and the latest Oculus Integration with Unity from the asset store. Unity version is latest official release, 2018.2.17f1.
More specifically said, we just want bloom to work but we can't seem to do so without having to set the intensity so high that our editor gets whitened out, and only then, you can see a slight bloom effect in the VR. HDR is enabled.
I hope your were using Rift. I may have to use PP stack soon for a project which need few effects. Btw, can you list the effects that were working for your?
