Fitted Mesh: “last call” for issues; release candidate “after the holiday”

secondlifeThe Lab’s Fitted Mesh project viewer has been out for a month, and has seen some good feedback from those who have been trying it out.

Already one update to the viewer has been released, correcting a number of problems, and the Lab has been working with content creators and users who have been providing feedback through the FITMESH project reporting on the JIRA.

However, Lab is keen to start progressing the project in the New Year, and so a “last call” for issues has gone out.

“If you’ve been seeing any issues with the current fitted mesh project implementation, or anything that needs to be added/changed, please make sure that the issues are filed by now, or as soon as possible,” Nyx Linden said at the Content Creation User Group meeting on Monday 16th December.

For those who missed the original announcement, Fitted Mesh is a means by which mesh garments are rigged to the collision bones of the avatar skeleton, allowing them the be resized as the avatar’s shape is changed using the Edit Shape sliders. In essence, it is the same approach as has been seen within Second Life and variously referred to as the “RedPoly method” or “Liquid Mesh”.

The technique uses both the existing bones in the SL avatar and an additional set of bones in order to work, and you can read more on it in my original preview article, if you’re not already familiar with the approach.

Oz Linden, also at the meeting, underscored the “last call”, saying, “To emphasise what Nyx said earlier … get your comments and issues in on Fitted Mesh ASAP so that we can do a release candidate after the holiday break.”

Quite when that release candidate will appear is unclear; there is a lot going on at the Lab, and several projects are likely to be vying for room in the release channel (although some will hopefully go to project viewer status first and give the rest some elbow room).

However, if you have been looking at the current Fitted Mesh viewer and wish to have input to the project, now is very much the time to do so. Similarly, if it is something which has been on your “to do” list, now is the time to move it to the top, or risking seeing your chance ot have input to the project, and influence on the Lab, vanish.

Firestorm meeting and Q&A December 14th: video and transcript

firestorm-logoOn Saturday December 14th 2013, the Firestorm team hosted another informal question-and-answer session. While the meeting was recorded, the Firestorm team are aware that many of their users have hearing difficulties, and / or prefer to read text. It is because of this that this transcript has been provided.

When reading it, please remember:

  • This is not a word-for-word transcript of the entire meeting. While all quotes given are as they are spoken in the video, to assist in readability and maintain the flow of conversation, not all asides, jokes, interruptions, etc., have been included in the text presented here
  • If there are any sizeable gaps in comments from a speaker which resulted from asides, repetition, questions to others etc,, these are indicated by the use of “…”
  • Timestamps are provided as guidance should anyone wish to hear the comments in full from any speaker on the video
  • Questions /comments were made in chat while speakers were talking. This inevitably meant that replies to questions would lag well behind when they were originally asked. To provide context between questions and answers, questions in the transcript are given (in italics) at the point at which each is addressed by a member of the Firestorm team, either in voice or via chat.

Please note: This transcript is provided for informational purposes only. As such, questions on technical issues relating to Firestorm and  / or project-specific questions cannot be answered here unless one of the Firestorm team drops by.

The TL;DR Summary

The numbers in braces are timestamps which refer to the section of this transcript where more details can be read, and to the section of the video recording where the relevant comments can be heard.

Main Discussion:

  • The next release: will most likely be a stabilisation of the code currently in 4.5.1 rather than introducing major updates, although this is still to be determined. LL have a lot coming down the pipe, which Jessica was hoping would be ready for inclusion in the next release, but that is looking unlikely unless something significant happens to change things [0:00:25-0:02:48]
  • Response to the beta has been good, around 120,000 downloads, of which around 6,000 are for the Windows 64-bit version. A number of people have subsequently reverted back to the 4.4.2 release due to issues. There are significant issues with voice, Mac users have encountered issues arising from Cococa (Mac and Voice issues covered later as well).[0:02:48-0:06:03]
  • Reference is often made to “Linden Bugs”. This does not necessarily mean they are the Lab’s fault; it simply means that the SL viewer has the same issues [0:06:03-0:06:53]
  • Firestorm releases are currently roughly four months apart. Ideally this should be two months, which is a target, but needs to be balanced with the risk of overwhelming the support volunteers (who need to both learn and support new releases). Therefore, it might mean a compromise of a release every quarter [0:06:53-0:09:40]
  • Voice issues: Vivox problem, LL have it as well. Firestorm have a series of videos demonstrating the problem. If a user on FS 4.5.1 beta has the issue, the recommendation is to revert to the 4.4.2 release [0:09:53-0:10:46]
  • The FS Windows 64-bit has been well received and feedback has been positive. Most people are reporting imporved stability rather than improved performance compared to the 32-bit version [0:11:10-0:12:56]
  • Oculus Rift is coming to Second Life [0:13:10-0:15:27]
  • Leap Motion is coming to Second Life – and the Firestorm Team have taken a lead in the integration work with the viewer [0:15:27-0:22:49]
  • Firestorm 4.5.1 beta and Firestorm release numbering explained [0:23:02-0:26:35]
  • Why Firestorm block versions and why Phoenix isn’t currently blocked [0:52:02-0:58:41; 1::0036-1:02:56]
  • Firestorm Q&As qill be monthly from January, alternating between 08:00 SLT and 16:00 SLT month-by–month [1:12:03]

Q&A Session:

  • Would it be an option to have different branches for people to download …? – includes discussion on why FS does not have nightly builds and on joining the FS beta testers [0:27:56-0:37:32]
  • Can we hope for more tattoo layers? [0:37:35-0:39:19] – reply includes reference to Linden Lab User Group meetings, the forums in which such questions can be asked
  • Will the new version [of Firestorm] be in 64-bit, and is Fitted Mesh coming? [0:40:00-0:47:40]
  • Why is IM and local chat so laggy in the beta version of Firestorm? (Mac build) – known issue, with both Firestorm (FIRE-12172) and LL JIRAs raised against it [0:47:40-0:49:47]
  • Why will music streaming not work on 4.4.2 with the new Mac OS upgrade? – Mac OS X 10.9 Mavericks issue reported under FIRE-10630 There is also a list of Cocoa bugs specific to the Mac build [0:49:47-0:52:02]
  • Dealing with inventory “jump” issues and bug regressions [0:52:02-1:00:36]
  • Are older versions of Firestorm also blocked from OpenSim when they are blocked from SL? – any version prior to 4.4.2 will unfortunately be blocked from OpenSim when blocked from SL. All versions of FS from 4.4.2 onwards can be individually blocked from grids [1:02:56-1:04:13]
  • Has the FS team ever considered working on a mobile Firestorm product? – includes the FS April Fools from 2013, and accessing Firestorm remotely [1:04:16-1:10:17]
  • Has the FS team considered “drawing a line” on how far they’re veer from the LL codebase (e.g. additional feature input, etc.), in order to improve the release cycle and lessen the maintenance overheads? [1:13:20-1:21:01]
  • What drives the FS team to do what they do? [1:21:40]
