I see different ones posted on .To periodically but I was wondering how to use them?
Please see the most recent updates in the "Where did the .com name go?" thread. Posts number 16 and 17.
I wouldn't bother. These shaders are made to improve the creator's own system, not yours. Create one of your own instead.
Further information on using the shader tool can be found here.Would probably help if I actually knew what they really were and how they are implemented first...![]()

And here's where you can view where each one is currently:Civil Twilight
Nautical Twilight
- Definition:
The period when the sun's geometric center is between 0° and 6° below the horizon.
- Characteristics:
The sky is still bright enough for outdoor activities, and the horizon is clearly visible. The most colorful skies are seen during this time.
Astronomical Twilight
- Definition:
The period when the sun's geometric center is between 6° and 12° below the horizon.
- Characteristics:
The sky is much darker, and the horizon becomes difficult to see. It is still bright enough to see the horizon and navigate by the brightest stars.
- Definition:
The period when the sun's geometric center is between 12° and 18° below the horizon.
- Characteristics:
It is the darkest phase of twilight. For observers, it is not technically considered true night until the sun has gone 18° below the horizon. However, the sky is dark enough for astronomical observations.
