ENBSeriesINI - Timeofday

ENBSeries INI Reference

The TIMEOFDAY (ToD) parameters allow for precise control of when ENB effects are applied to the screen based upon Skyrim's weather system. The effect parameters themselves are delineated using dawn, sunrise, day, sunset, dusk, and night variants. The ToD parameters are derived directly from the DefaultClimate [0000015E] and DefaultSkyrim [00000812] TNAM records for Sunrise and Sunset Begin/End times in Skyrim.esm. Calculations for setting ToD parameters --given the plugin record values of the weather system-- follow the parameter descriptions below.

The following ToD definitions apply to the position of the Sun from the perspective of a location at lowest altitude and with East/West horizons visible without land interference (near cow tamriel 0 40). Instead of using datetime format, numeric format is expressed in floating point (0.0000...23.9999) based on the twenty-four hour day and expressed in military time. For brevity, only one decimal place is shown in the examples.

DawnDuration

DawnDuration=(0.0...23.9)

Duration from the time at which light first appears in the sky in the East until the time the sun appears in its entirety over the horizon.

SunriseTime

SunriseTime=(0.0...23.9)

This setting is the time that the sunrise occurs in game.

DayTime

DayTime=(0.0...23.9)

This setting is the time that the middle of the day occurs in game.

~z929669  Talk Propose change to: "The time at the midpoint of day."

SunsetTime

SunsetTime=(0.0...23.9)

This setting is the time that the sunset occurs in game.

~z929669  Talk Propose change to: "The time that light first begins to fade from the sky."

DuskDuration

DuskDuration=(0.0...23.9)

This parameter is the duration that the transition from sunset settings fades to night settings in game hours. Basically this is the time from when the sun sets and can't be seen (SunsetTime) to the time set for NightTime.

~z929669  Talk 03:20, March 15, 2022 (UTC) Propose change to: "Duration (hours) from the time the sun disappears from view over the ocean until all sunlight fades from the sky."

NightTime

NightTime=(0.0...23.9)

This setting is the time that the middle of the night occurs in game.

~z929669  Talk Propose change to: "The time at the midpoint between the time at the end of DuskDuration and the time at the beginning of DawnDuration."

Understanding the Durations

The two Duration settings can be confusing to understand. They are essentially timers for the fade effect between two sets of parameters (Reference).

Math

DawnDuration:: SunriseTime = (DawnStart + DawnDuration)

DuskDuration: SunsetTime = (DuskStart + DuskDuration)

Dusk/Dawn ends at SunsetTime/SunriseTime

Game Times

Game time is configured within the Climate records under TNAM - Timing, but there are only Begin and End times for Sunrise and Sunset. These are the time frames the game will fade from one set of values to the next. However, these values to not correspond SunriseTime and SunsetTime for ENBSeries. These times are determined by the moment the Sun becomes visible and the moment it disappears from view, which will be the halfway point between the TNAM - Timing values.

Using Cathedral Weathers as an example (current at the time of posting) the process is as such:

1. Open CW plugin to see the following times set:

   Sunrise

   Begin = 5:00:00 AM DawnStart End = 9:00:00 AM DayTime

   Sunset

   Begin = 5:00:00 PM DuskStart End = 9:00:00 PM NightTime

2. Loading the game and using the Wait Menu, one can determine the sun peaks into view at 7AM (SunriseTime)
3. Continuing this method it can be seen the sun disappears from view at 7PM (SunsetTime)
4. Now all the values are determined to solve for the Durations:

   DawnDuration:: SunriseTime = (DawnStart + DawnDuration) 7 = (5 + DawnDuration) (7 - 5) = (5 + DawnDuration - 5) 2 = DawnDuration

   DuskDuration: SunsetTime = (DuskStart + DuskDuration)

Old

Math

DawnDuration: (SunriseTime - DawnDuration) = DawnStart Dawn ends at SunriseTime

DuskDuration: (SunsetTime - DuskDuration) = DuskStart Dusk ends at SunsetTime

Example

DawnDuration=2 and SunriseTime=7 (7 - 2) = 5

NightTime values will start to transition to Sunrise values at 5am and will complete at 7am.

Game Times

Game time is configured within the Climate records under TNAM - Timing, but there are only Begin and End times for Sunrise and Sunset. Game time at the moment the Sun becomes visible is SunriseTime, and the moment it disappears is SunsetTime. From there, the Durations can be calculated.

Using Cathedral Weathers as an example (current at the time of posting) the process can be walked through as such:

1. Open CW plugin to see the following times set:

   Sunrise

   Begin = 5:00:00 AM DawnStart End = 9:00:00 AM DayTime

   Sunset

   Begin = 5:00:00 PM DuskStart End = 9:00:00 PM NightTime

2. Loading the game and using the Wait Menu, one can determine the sun peaks into view at 7AM (SunriseTime)
3. Continuing this method it can be seen the sun disappears from view at 7PM (SunsetTime)
4. Now all the values are determined to solve for the Durations:

   (SunriseTime - DawnDuration) = DawnStart (7 - DawnDuration) = 5 DawnDuration = 2

   (SunsetTime - DuskDuration) = DuskStart (19 - DuskDuration) = 17 DuskDuration = 2

   DawnDuration=2.0
   SunriseTime=7.0
   DayTime=9.0
   SunsetTime=15.0
   DuskDuration=2.0
   NightTime=21.0
