Quick answer: Feed the sun's altitude (dot of sun direction and up) into the sky shader and lerp horizon and zenith colors with a smoothstep around the horizon band.

At a fixed hour your Godot sky snaps from blue to black with no orange twilight in between. A WorldEnvironment sky should blend its colors continuously as the DirectionalLight3D dips below the horizon, not toggle at a magic number.

How to fix it

1. Compute sun elevation

In a custom Sky shader or script, take dot(normalize(sun_direction), vec3(0,1,0)) to get the sun's height, then map it to a 0-1 day factor with smoothstep(-0.1, 0.1, elevation) so the transition spans the horizon.

2. Lerp the gradient colors

Use that factor to mix() between day and night horizon and zenith colors, and add a separate warm twilight tint peaked near elevation 0 for the dawn/dusk glow.

3. Sync ambient and fog

Drive Environment.ambient_light_color and fog color from the same factor each frame so the sky, fog, and ambient stay consistent through the transition.

Catching the ones you can't reproduce

The hardest version of this to fix is the one you can't reproduce — it only happens on a player's hardware, OS, driver, or save state, under conditions that simply aren't present on your machine. A report that says “it crashed” or “it froze” gives you nothing to act on, so the bug survives release after release while quietly costing you players.

Automatic error capture closes that gap. Each failure arrives with its full stack trace, the device and OS, the build number, and a breadcrumb trail of what the player did right before it broke, so even a failure you have never seen becomes a specific, reproducible issue. Fold identical failures into one signature ranked by how many players each hits, and your worklist sorts itself worst-first instead of arriving as a stream of vague complaints.

This is where a tool like Bugnet earns its place. Its SDK captures every Godot error automatically with the full stack trace plus device, OS, memory, build, and game-state context, folds duplicates into one grouped issue with an occurrence count, and ties each to the build it first appeared on — so you fix the problem that hurts the most players first and confirm it is gone when its signature disappears from the next release.

Most of the time the fix is small. Seeing the failure clearly is the part that actually costs you.
