360 Photo display low quality in Meta Quest

[dormouse]

Dear all,

is there any tips of displaying high resolution 360 photos in Meta Quest2/3 ?
i tried many combinations of import setting of 360 Photo, but only get poor quality of display.
With some panoramic video/image players, e.g.VR skybox player, the 23K *11k photos (200mb) are displayed properly/smoothly with high resolution.

However, with in Unity, i never achieved same resolution as the Video/Photo Player.
Below 40962048 (maxi size), it displayed properly and smooth, but blur details.
Above 40962048, e.g. 81924096, it displays higher resolution but with jittering/shimmering details.
here is the import setting of my 360photos,
-RGB(A) Compressed ASTC 44 block
-Gerenation Mipmap: off

also tried with Cubemap and Panoramic skybox shaders on a 3D sphere material, the same results.

which means we never achieve Photo/Video Player’s resolution with Unity? is there any suggestions about Image size, resolution, import settings, project settings ?
also tried anti-aliasing of URP, doesn’t help.

Try using composition layers: About Composition Layers | XR Composition Layers | 1.0.0

This allows you to submit the 360 to the XR compositor directly, where it will most likely display at a higher quality.

If you’re using Meta’s plugin instead of OpenXR, they have their own similar thing.
