Troubleshooting Volumetric Clouds rendering issues
Prevent far-away clouds from disappearing when the camera moves along the y-axis, especially when traversing the clouds.
Symptoms
Far-away clouds disappear as the camera moves along the y-axis when the Rendering Space is set to World.
Cause
To enhance performance, the default number of steps used to evaluate the clouds' transmittance is low. This causes the clouds further away to disappear as the camera moves along the y-axis.
Note: In Unity 6, the default rendering space was changed to World, making this issue more noticeable than in Unity 2022 LTS, where Camera was the default setting.
Resolution
To prevent far-away clouds from disappearing, increase the Num Primary Steps value in the Quality section of the Volumetric Clouds override.
Important: A high Num Primary Steps value can hinder performance. Adjust this setting with caution.
