As always, please refer to the server deployment thread for the latest news and information.
There was no deployment on the Main (SLS) channel on Tuesday August 19th. All three RC channels should receive the same server maintenance project on Wednesday August 20th, aimed at fixing a crash mode.
SL Viewer Updates
The library refresh viewer, version 22.214.171.1242638 was promoted to the de facto release viewer on Monday August 18th. This viewer contains an update to a large set of libraries used by the viewer to provide security, stability and consistency improvements to this and future viewers – release notes.
This leaves just the Experience Keys project viewer (due for a refresh in week 34), the Oculus Rift project viewer (due to undergo updates in the coming weeks following the Lab’s receipt of Oculus Rift DK2 headsets), and the RC / experimental log-in viewer in various visible viewer channels.
Group Ban Notifications JIRA
A couple of group ban issues have been raised on when and how notifications on ejection and banning are displayed by the viewer since the arrival of the group ban capabilities (or aren’t displayed, as the case may be) – see BUG-2054 and BUG-5928. Cinder Roxley has submitted code as a part of rectifying BUG-2054, and the Lab are looking and what they need to do to ensure consistent and logical notifications are given.
Materials and Related News
Materials Rendering via Basic Shaders
Geenz Spad contacted me over the weekend to point-out BUG-2077, a feature request that would enable all users that enable Basic Shaders to see a subset of materials functionality present in Advanced Lighting Model. Commenting on the JIRA, Geenz notes:
The performance impact won’t be noticeable on the vast majority of GPUs that support at least atmospheric shading and basic shaders, and should generally be much faster on systems that have trouble with ALM. On top of that, this should enable materials to work in water reflections and refractions to some extent.
However, he also notes a number of constraints:
- Maximum number of lights will go unchanged
- Projectors still will not work
- Gamma correction will only be approximated.
In pointing the JIRA out to me, Geenz said, “A proposal has been submitted to LL regarding materials in basic shaders. I’ve started working on materials in basic shaders already, though work will be moving along slowly so definitely don’t expect this to done for a little while.”
At the same time, Geenz is also working on fixing projector reflections not respecting the environment intensity parameter (see BUG-2056). Currently, projector reflections are treated as specular reflections rather than environment reflections (see below). This fix would correct that.
Again speaking to me about the work, Geenz said, “This is something that I largely started working on while fixing the environment intensity bug on projectors. Projectors didn’t seem to make a whole lot of sense in their previous state, and since we have enough information to actually do “glossy” reflections with projectors as it is, it made much more sense to just have glossiness tied to the existing glossiness material parameter.”
A further JIRA submitted by Geenz (see BUG-2067) proposes a means of improving the use of projectors to create surface “reflections”. Geenz provides the explanation thus:
Presently projectors have very strange behavior. Depending on a surface’s environment intensity, they get blurrier the more intense they are, and the reflections “fatten” depending on how intense the reflections on the surface are. This doesn’t really make a whole lot of sense.
Depending on how glossy the surface is, projector reflections should become sharper for higher gloss values and blurrier for lower values. On top of that, projector reflections shouldn’t “fatten” based upon intensity; this makes them unusable for decent looking reflections.
This feature makes use of the glossiness parameter to calculate the “gloss” of projector reflections.
Mac Cocoa applicationShouldTerminate Issue
Cinder Roxley has pointed-out a problem with the Cocoa-specific applicationShouldTerminate function within the viewer, which she explains thus:
Say you are logged into sl, and you open appstore and there is an update that needs a restart to complete. Normally you click restart and it shuts down all apps completes the update and when you login your apps are reopened. Because the viewer is sending a bad value back to OSX, OSX will not close it, and it stops the restart from happening.
STORM-2053, submitted by Cinder provides a fix for this problem.
Work is continuing to refine the SL mirrors project (see my report and JIRA (BUG-2055 initiated by Zi Ree of the Firestorm team). There has been some lively lively debate on the JIRA over the course of the last week. The more recent progress has been focused on getting mirrors to work with the Advanced lighting Model (ALM) active.
On top of everything else he’s doing, Geenz Spad has been providing pointers for some the work as well as demonstrating how mirror surfaces could benefit if they are made to work with materials, as shown in the images below.
There is still a fair amount of work still to do before it is likely that the Lab look at any proposal arising from this. I’ll continue to update on progress as it is made, as I also hope to with Geenz’s work with projectors and materials as noted earlier in this report.
