Second Life Preview 1.9.1 Release Notes


Note: "Undocumented Features/Changes" were not mentioned in the official release notes for one reason or another. These are resident-added to this page.

Build 9, Apr 13, 2006

Features

  • Hardware lighting
    • Any primitive in Second Life may be turned into a light
      • Light properties are radius, color, intensity, and falloff
    • New options in the Preference panel indicate the type of lighting you want to use
      • "Sun or Moon only" is best for low-performance hardware
        • Everything in-world is lit in real time by the sun or moon only
      • "Nearby Lights" is available for any hardware configuration
        • Everything in-world is lit by sun or moon and up to six nearby light sources
      • "All Lights" is available on systems with GPUs supporting Vertex Shaders
        • Objects in-world, and terrain, are by sun or moon and all lights
        • Avatars and attachments, trees and grass are lit by sun or moon and up to six nearby light sources
      • "All Lights + Shadows" is available only to high-performance systems
        • Includes features in "All Lights" above plus the ability for the sun and moon to cast shadows in-world and on terrain
    • More information about the new lighting system is available here:
  • Flexible objects
    • Cube, prism and cylinder primitive types can now be made flexible as a client-side effect
    • Simulation parameters for material and responsiveness to gravity and wind
    • Objects that are flexible cannot be physical and are always phantom
    • Use of these is currently limited to preserve framerate as they increase amount of client-side processing
  • Occlusion culling
    • Frame rate is improved when objects that would normally be rendered are hidden from view
    • FPS will be significantly improved when inside a structure
      • Windows or other transparent surfaces will decrease effectiveness as objects in view will be rendered, whether or not they are within the structure
    • Toggle with CTRL-SHIFT-o on all platforms
  • New "Click Action" functionality for objects
    • Object creators can select a default left-click action for objects:
      • Touch (default), Sit, Buy, Pay, or Open
    • These actions happen immediately when a resident left-clicks on the object, without a menu
    • Builders set the action in the build tools "General" panel, at the bottom
    • Click actions override touch events for scripts
      • If you want the touch behavior, be sure "touch (default)" is the click action
    • You can't set "Buy" as the action unless an object is for sale
    • "Sit" should be useful for both chairs and vehicles
    • "Open" should be useful for vendors that sell packaged objects
  • Updated functionality for the Top Scripts/Top Colliders dialog
    • Improvements allow Estate owners to return or disable offending objects
      • Disabling an object makes it non-physical and disables all scripts
  • Classified ads now have an auto-renew option
    • Checking the "Auto renew each week" checkbox in Profile > Classifieds will cause your classified to be republished instead of expiring after one week
    • You will be charged the same listing price as the initial classified
    • To change the listing price, you need to make a new classified
  • Universal Binary installer for Mac clients is now standard
    • PowerPC and Intel Mac versions are now bundled together in one "Universal Binary" installer
    • Minimum required version for Second Life is now 10.3.9

New LSL Functions

  • llHTTPRequest
    • Added new LSL call & event to support HTTP access from external scripts
    • LSL Function usage:
      • key llHTTPRequest(string <url>, list <parameters>, string <body>)
        • Send HTTP request to <url> with <parameters> and <body>, returning key uniquely identifying the request
        • Currently, the only supported parameter is the following key/value pair: HTTP_METHOD, <method name>
    • LSL Event usage:
      • http_response(key <request_id>, integer <status>, list <metadata>, string <body>)
        • Called when a pending HTTP request <request_id> completes with the HTTP <status>, <metadata> and response <body>
        • This facility supports GET, PUT and POST methods, X-SecondLife-headers, text/* MIME types, and transcoding of body contents to LSL's Unicode strings
  • llGetParcelFlags
    • Get the parcel flags (PARCEL_FLAG_*) for the parcel including the point pos
    • Returns an integer that is a bit field of flags
    • This bitfield can be ANDed with a flag to see if that flag is set for that parcel
    • Usage:
      • integer llGetParcelFlags(vector pos)
    • Example:
      • if (llGetParcelFlags() & PARCEL_FLAG_ALLOW_CREATE_OBJECTS) llOwnerSay("You may create objects in this parcel!");
    • Bitfields:
      • PARCEL_FLAG_ALLOW_FLY
        • Used to determine if a parcel allows flying
      • PARCEL_FLAG_ALLOW_SCRIPTS
        • Used to determine if a parcel allows outside scripts
      • PARCEL_FLAG_ALLOW_LANDMARK
        • Used to determine if a parcel allows landmarks to be created
      • PARCEL_FLAG_ALLOW_TERRAFORM
        • Used to determine if a parcel allows anyone to terraform the land
      • PARCEL_FLAG_ALLOW_DAMAGE
        • Used to determine if a parcel allows damage
      • PARCEL_FLAG_ALLOW_CREATE_OBJECTS
        • Used to determine if a parcel allows anyone to create objects
      • PARCEL_FLAG_USE_ACCESS_GROUP
        • Used to determine if a parcel limits access to a group
      • PARCEL_FLAG_USE_ACCESS_LIST
        • Used to determine if a parcel limits access to a list of residents
      • PARCEL_FLAG_USE_BAN_LIST
        • Used to determine if a parcel uses a ban list
      • PARCEL_FLAG_USE_LAND_PASS_LIST
        • Used to determine if a parcel allows passes to be purchased

Build 25, May 11, 2006

Important Update

With release 1.9.1, we have begun the process of converting the Second Life render pipeline to use GLSL (OpenGL Shader Language). The reason for this is to accommodate some of the changes we are planning to introduce to the graphics engine, including the new lighting model,

Unfortunately, during our testing process (which includes Preview) we have found that many graphics drivers either do not fully support GLSL, or have significant performance issues with GLSL.

As a result, we have decided to scale back our initial introduction of GLSL support. Instead of using GLSL for the majority of our rendering, we are initially only using GLSL for rendering avatars and for ripple water. Previously we were using Cg (another shader language) for these features, and a non shader fall back is still available.

What This Means

  • The new lighting model currently only supports "Sun/Moon only" and "Nearby local lights". The "Nearby local lights" option is still a significant improvement to the "local lights" option in 1.9.0, largely due to the fact that it has a relatively small performance impact on most machines. The limitation of this option however is that only the six lights nearest your avatar will be used to light the scene.
  • Some subtle rendering effects that were available in Preview with shaders enabled will not be available yet (specular highlights and some advanced fog effects).

Coming Soon

  • We hope to be able to provide the "All local lights" and "Shadows" lighting options soon, but these rely on GLSL and will have to wait until we have had more time to test the new shaders. We hope to make this available in the next release.

Bug Fixes

  • Fixed crash when retexturing your avatar
  • Fixed a bug that was causing objects to be incorrectly culled
  • Fixed a bug which added a skirt when changing vatar textures
  • Users can no longer rename themselves temporarily
  • Alpha objects no longer render on top of flexible alpha attachments
  • Flexible objects no longer have a larger editing glow
  • Light color picker swatch now shows current color
  • Mute IM->e-mail if the sender is muted
  • Map beacon now removed when clear button is pressed
  • Changing Cube to Sphere to Cube in building block type no longer results in a prism
  • Disabled one-click 'Sit' for flexible objects
  • Animated textures now work more smoothly on flexible objects


Build 26, May 15, 2006

Version 1.9.1 was reversioned to Version 1.10, see version 1.10 for a continuation of this versions release notes.
