EDIT: It happens only on Oculus, so I made a post on their forums: https://forums.oculus.com/viewtopic.php?f=37&t=23062&p=268281#p268281
and edited this post.
===================
A moving platform uses reflections from a box-projected probe (baked to file, but it doesn’t matter).
The probe is attached to the moving platform as a child. The reflections are shaking, like lagging a frame behind sometimes - but only in Oculus view.
Maybe Unity is sending reflection data to meshes too early or too late, compared to Oculus rendering?
Do you know about this issue?
