This is a screenshot of the volumetric clouds with the passthrough mode shows the HMD screen. As you can see, the clouds are not rendered on the right eye. This happens when you enable “r.VolumetricCloud.HighQualityAerialPerspective” in UE5.0 (UE4.27 has the same bug).
The effect gives the clouds the hue of the atmosphere even if they are very far away, as you can see in the left screenshot. When it is disabled, the cloud shadows are less blue when they are very far away.
I am pretty sure that this is a bug. If anyone knows how to fix it or has a workaround, that would be wonderful.
