At night, underwater god rays originate from the opposite angle of the moon, leading to an unnatural look as there is no visual light source that they originate from. Attached is a video demonstrating the issue that I have increased the brightness of for visibility.

Steps to Reproduce:

1. Enter any world with Ray Tracing on
2. Set the time to 16000
3. Go underwater and look at the direction of god rays relative to the moon

Observed Results:

The underwater god rays originate from the opposite angle of the moon, and the shadows are in the reverse direction

Expected Results:

The god rays should originate from the same angle as the moon and the shadows should be displayed at the right angle, as that is where the physical light source is visually located, and is also how it functions above ground.
