I am noticing some unwanted rendering issues of Niagara particles in VR and when building to the Quest 2. I am using UE 4.26.
I have a simple scene with some particles, a ground plane, a point light and the default VRPawn.
When I build and play, the particles seem to render properly when I look directly at them, but if I turn my head to one side or the other, they pop off, or render only in one eye. You can see the render glitches in the video below as I turn my head away from the particles. Notice the asymmetrical rendering in left and right eyes.
What is causing these render issues? How do I solve it? Can I expect more reliable rendering when using Cascade?
