The following notes are taken from the TPV Developer meeting held on Friday December 6th. A video, courtesy of Northspring, can be found at the end of this report. The numbers in braces after each heading (where given) denote the time stamp at which the topic can be listened-to in the video.
Release Channel Viewers
Name Updater Release Candidate
[00:17-01:40]
The Name Updater RC viewer, also released on December 3rd, has been updated to version 3.6.12.284506. This contains no functional changes to the viewer itself but contains two sets updates, hence the odd name.
The first of these is a fix for the viewer updater where problems can occur if a new update to the viewer is downloaded by the updater but deleted somehow prior to the installer itself being executed. The second set of updates cover:
- Changes to how the viewer packaging is done and cleans-up how the viewer channel (used to recognise the viewer and allow it to connect to the SL servers when logging-in) is distributed and established
- Makes some changes to the viewer start-up parameters
- Changes the package names to a uniform format which is the same for all of the operating system platforms.
The aim of these changes is to further improve the viewer build process and reduce the number of places changes have to be made in order to change the viewer channel name when building different flavours of the viewer (LL’s own or a TPV).
The RC has been performing well in terms of low crash rates, etc., and looks set to be promoted to the de facto release viewer in week 50 (week commencing Monday 9th December), and so will see-out 2013 as such if this is in fact the case.
Google Breakpad
It is possible a further Google Breakpad RC may appear in week 50.
Maintenance Release Candidate
[02:00-02:16]
The Maintenance RC viewer 3.6.12.284430, released on December 3rd suffered an abnormally high crash rate, prompting it to be withdrawn in order for it to be looked at and crash issues diagnosed / fixed. Once these issues have been dealt with, the viewer will be returned to the release pipe.
Project Interesting Viewer
[39:24-41:07]
The Project Interesting (aka “viewer-interesting”) RC viewer has been in RC for a while and is suffering a high number of crashes, which are currently being investigated by the Lab. Unlike the Maintenance RC viewer, it has been left as an RC simply because issues are being found with it, because of both the number of people using it and the broad range of systems on which it is being run and which the Lab couldn’t possibly account for in their own testing.
At the moment, the Lab are trying to put together an update for the viewer, but they still have a couple of “pretty serious” crash issues which have yet to be resolved. However, the hope is that this may actually make it out into the world before the no change / code freeze window comes into force on Monday December 16th, which affects all server releases and all viewer release channel releases. This would allow the updates made to get further “in the field” testing during the code freeze / holiday period.
That both the Project Interesting and Maintenance RCs are experiencing issues is something of a validation of the new viewer release process introduced by the Lab earlier this year, in that the problems being encountered with both of these viewers are not blocking the viewer pipe, unlike the situation of just over a year ago, where a series of crash issues with the old beta viewer completely halted all significant viewer updates.
Fitted Mesh Project Viewer
[02:20-03:16 / 32:05-39:20]
As noted in part 2 of this week’s report, the Fitted Mesh project viewer received a set of updates (including new avatar skeleton files) in the form of release 3.6.12.284458. The project viewer has so far received a very low number of downloads – somewhat unsurprisingly – with the total number of people using the viewer thought to be under 2,000. This means that it hasn’t as yet been used widely enough to generate meaningful crash statistics.
The response to the skeleton changes within the viewer has been “good”, and the viewer has seen a reasonable number of JIRA issues raised under the FITMESH project, etc., although the Lab cautions against anyone using the changes contained in the viewer in anything other than an experimental version of their own viewer until such time as the code reaches a Release Candidate status. The latter will not happen before the end of 2013, although there may be a further project viewer update for Fitted Mesh before the end of the year.
One thing which may happen when the viewer is approaching a release status is that it will bring with it a “significant bump” to the viewer version number, not the least of which is because users on viewers without the code may see some bizarre, or at least oddly fitting clothing on avatars using garments weighted to use the new system, as noted in my launch preview of the Fitted Mesh project.
Overall, it appears that the Lab is “pretty happy” with the way the work is developing, although they would like to see more people involved in using / testing the viewer, particularly anyone proficient in rigging mesh garments, etc, especially given the nature and state of the project, as Oz Linden pointed-out:
This is one of those times when things are in flux and can be changed… We have never made changes to the avatar skeleton casually, and we’re making a round of changes now; we’re wildly unlikely to make another round of changes for years. So if there is feedback to be had, this is the time to have it.
So if you are a creator and do have an opinion on how things might be better handled within the Fitted Mesh solution, now is the time to be involved and potentially influencing the Lab’s thinking. not every idea put forward may be taken-up; but on the other hand, waiting until the changes have been made and the viewer released will certainly mean that any ideas someone may have will have passed their sell-by date.
The Delay in Opting for this Solution
Part of the general feedback voiced when the Lab announced the Fitted Mesh viewer came in the form of questioning why it took the Lab so long to reach the decision to go with the approach. Part of the reason appears to be that mesh deformation and Server-side Appearance projects required the same expertise with the Lab to be applied to them, and so were vying with one another for manpower – and the decision was made to give the SSA project priority.
Oculus Rift Update
[24:46-26:26]
During the Server Beta meeting on Thursday December 5th, VoidPointer Linden indicated the work on making the viewer operate with the Oculus Rift headset was now “feature complete”, and that a (presumably project) viewer will be appearing “soon” with support for the headset. How soon is open to question, given VoidPointer had to be somewhat circumspect. However, following the TPV developer meeting, it appears that “soon” might actually be a little more in the realm of “later” than may be the case.
