Tutorial: EEP Personal Lighting

The Environment Enhancement Project (EEP) is a mechanism to provide region and parcel holders and individual Second Life users, greater control over there personal environment or the environment for their region / estate or parcel.

This tutorial is designed to walk you through the essentials of EEP, including the terminology used.

Introduction
Part 2: Personal Lighting

Part 3: Fixed Environments
Part 4: Day Cycles
Part 5: Importing Windlights and EEP LSL Resources

It is divided into a number of sections:

  • The introduction, covering EEP capabilities, concepts and settings permissions; viewer menu options; the region / estate and parcel controls; and how to create / edit EEP asset types.
  • This section, using the the Personal Lighting floater to adjust the environment around you in your own view only.
  • Using the Fixed Environment controls and options to control individual Sky and / or Water settings.
  • Using the Day Cycle controls and options to create complete day / night cycles, including different settings defined by altitude.
  • Importing Windlight Settings and EEP LSL Resources.

If you are coming fresh to EEP, it is recommended to read the introduction first.

Note that this tutorial has been written using the official EEP project and RC viewers. TPV implementations of EEP (when available) may vary.

What Is Personal Lighting?

With Windlight, SL photographers and machinima makers are familiar with being able to visit an in-world location and using the environment tools within the viewer to make changes to the environment to suit their needs: move the sun higher or lower in the sky, move it around the sky, change the cloud density, alter the horizon haze, etc.

However, as EEP assets have permissions associated with them, this may not always be possible: if a No Modify asset is applied to a region/estate or parcel, then things like the Sun position, the clouds, etc., cannot be altered.Instead, visitors can do one of two things:

  • They can opt to apply one of their own EEP assets to themselves, and then tweak that to suit their needs.
    • However, doing so means the applied settings probably won’t offer a reasonable match to the location’s actual environment, which might be required, and trying to get it to more closely resemble to location’s environment is likely to be a painstaking task.
  • They can use the Personal Lighting option to take a local “snapshot” of the environment (visible only in their own viewer), and then adjust the settings for that snapshot.
    • This allows fast tweaks to be made to how the location’s environment is seen. However, the changes made cannot be used to create a new EEP asset or modify and existing EEP asset; thus, the No Modify aspect of the environment being tweaked is preserved.

Notes:

  • Any changes made to the environment are only visible in your viewer.
  • The changes you make via Personal Lighting will persist until you log out or select World > Environments > Use Shared Environment.
  • While primarily designed to be used to major environment adjustments where No modify EEP assets may otherwise prevent you from doing so, Personal Lighting can be used to adjust any environment  – but remember, the changes you make cannot be saved.
    • If you are in a location where the environment can be modified, and you wish to make adjustments to it and then save those changes, you should used the Fixed Environments floater.

The Personal Lighting Floater

As noted above, the Personal Lighting floater allows you to make changes to a location’s environment that are only seen in your viewer – although they will remain in place until you either select World > Environments > Use Shared Environment or log out of Second Life.

The floater is a subset of options found in the Fixed Environments – Sky floater, and are summarised below.

The Personal lighting floater
  1. Ambient Colour and Density pickers: set the ambient sky and cloud colours –  simply click on the required picker, select the required colour and use the slider for setting the colour density.
  2. Haze sliders: use to adjust the atmosphere and horizon haze. If you’ve not used them before, the simplest way to understand them is to experiment with them.
  3. Scene Gamma: set the overall brightness.
  4. Position trackballs: use the Sun / Moon image on the trackball to adjust the position of the Sun and / or Moon.
    • If the sun/moon image on a trackball is dimmed it is below the horizon in-world, use CTRL-left-click and drag to raise it above the horizon (or conversely, to move it below or onto the horizon.
  5. Glow and brightness sliders (Sun and Stars only): sliders for setting glow and star brightness. Note that with stars:
    • To hide them in low daylight settings, set to 0.
    • If those who have Advanced lighting Model enabled in the viewer will be able to see stars “twinkle” if they are set bright enough
  6. Show beacon: display a local beacon (your view only, and also accessible via the beacons option World > Show > Beacons Ctrl-Alt-Shift-N).
