|EEP, the Environment Enhancement Project, is a set of environmental enhancements designed to replace windlight XML settings to control the water and sky environments seen in Second Life, and provide a wide range of additional capabilities for region holders, parcel holders and general users. It represents a fundamental shift in how environment settings are used and applied
In brief EEP:
In addition, key aspects of EEP are:
Table of Contents
This tutorial is designed to walk you through the essentials of EEP, including the terminology used. It is split into a number of sections:
- Terminology and Concepts – key terminology and concepts with EEP.
- The viewer UI elements associated with EEP.
- An overview of creating and editing EEP assets.
- An overview of applying EEP settings
- Breakdowns of the floaters used to create Sky, Water and Day Cycles in EEP.
- An overview of importing windlight XML files into the viewer and saving them as EEP settings / assets.
- A summary of EEP LSL resources with links.
Some of these sections are self-contained, other can be used together (e.g. creating assets, using the Sky, Water and Day Cycle floaters, and applying EEP settings). To further assist referencing, major topics appear on their own page – please make sure you use either the table of contents or the page numbers at the foot of each page for ease of navigation.
Official information on EEP can be found in the EEP section of the SL wiki.
Note: at the time of writing this piece, the official Second Life viewer – version 126.96.36.1990188, dated April 15th (or later) to see / use EEP capabilities. However, TPVs will be releasing version supporting EEP in due course.
Terminology and Concepts
EEP uses some key terminology that should be understood.
- Settings: used to define the environment you see. There are three settings types:
- Sky: define the atmosphere and lighting for a day (or night); the movement, density, etc., of the clouds; and the appearance of the Sun and / or the Moon (which remain in a fixed point in the sky).
- Water: define the appearance of Linden Water (prim or mesh animated water is not affected): water colour and reflection; wave movement; amount of light refraction, etc.
- Day Cycles: collections of Sky and Water settings that are combined to present a dynamically changing environment over a user-defined time period representative of a “day” (by default this is set to the legacy Second Life day / night cycle of 4 hours, but can be extended out to represent physical world time periods of up to one week).
- Note that Sky and Water settings are referred to as Fixed Environments.
- EEP assets: physical “containers” for storing EEP settings. These are inventory items that by default, are stored in the new Settings folder in your inventory (see below), they are split into three types:
- Sky – Sky settings. Icon: a blue sky with clouds.
- Water – Water settings. Icon: a water droplet.
- Day Cycle – for Day Cycles. Icon: a split Sun / Moon.
- EEP assets (permissions allowing) can be exchanged, given away, and / or sold through a store or via the Marketplace.
Note that EEP settings are:
- Created or edited using their corresponding EEP asset (e.g. to create Sky settings, you use the Sky asset type).
- New EEP assets can be created directly from inventory, just like any other system inventory asset type (notecard, clothing item, gesture, script, body part).
- Creating / editing EEP assets and settings is covered in depth in my EEP tutorial.
- By default stored within a new system folder in inventory – the Settings folder. This folder may be hidden until such time as an EEP asset is created.
There are a few notes on permissions associated with EEP settings / assets.
- Copy/no-copy: EEP settings assets may never be marked no-copy. A person who owns a setting object may always make a copy of it in their inventory.
- Transfer/no-transfer: the no-transfer permission is persistent. If you import any no-transfer day or water setting into a day cycle, that day cycle will also become no-transfer. Once saved, this change can not be undone.
- Modify/no-modify: these permissions behave as normal.
EEP Library Assets
EEP includes a collection of Sky, Water and Day Cycles, together with a set of textures that can be used for clouds and / or to replace the Sun and Moon, etc.
- These are located in Inventory (CTRL-I) → Library → Environments.
- They can be used in once of two ways:
- Unmodified, directly from Library → Environments.
- By copying them to your inventory (e.g. to your own Settings folder, if it is visible through the creation of an EEP asset; if not, any other folder can be used), where they will become modifiable, allowing you to adjust them / use them to create your own settings.
- See my EEP Tutorial for editing / modifying EEP assets and settings.
Differences to Windlight
- EEP settings are stored in inventory assets, not as XML files saved to your computer.
- Because they are server-side, EEP settings are by default seen by any viewer affected by the. This can mean:
- Parcel owners using a specific set of environment settings no longer have to request visitors manually switch to them.
- Settings are no longer dependent on visitors to a parcel with a custom environment having the precise Windlight XML file stored on their computer.
- EEP setting do not require any external storage (e.g. Dropbox) in order to be shared with other users, if they are to be given away.
