Proper Direct Lighting, Skybox Post Processing and Fog during Rain/Weather

During Weather Events (Rain, Thunderstorm, Snow, Blizzard), the Sun/Moon (Direct Light) suddenly disappear, the Skybox turns into a monotone gray, and the Volumetric Fog vanishes. This degrades the visual quality of Vibrant Visuals, making the game appear like regular Minecraft.

What is suggested:

• Direct Lighting (Sun/Moon) should still be present (in presumably lower intensity) without being completely disabled during weather events.
• The Skybox should appear with various gradients, incorporating Bloom and Tonemapping to emphasize the Sun/Moon behind the "clouds".
• Volumetric Fog should be more prominent during weather events, in direct correlation with the first two.

TLDR; improve graphics during weather events, because currently it looks like regular Minecraft despite of Vibrant Visuals being enabled.

(P.S: I have tried every resource pack, even trying to create my own and I discovered that it is all within the constraints of Vibrant Visuals)
