I am using Quest 2 In project Most of the model shimmering
What do you mean by shimmering? Can you share a video please?
Is it related to this issue? Edge of model flickering in immersive VR
Without seeing a video or repro, it sounds very much the same issue as Edge of model flickering in immersive VR where the resolution of the display and sharp, contrasting edges is the limitation and is also apparent in non PlayCanvas experiences
