2016 SL project updates 34 (1): server, viewer, wiki

Binemust; Inara Pey, August 2016, on Flickr Binemustblog post

Things are still a little quiet, so not a lot to report at the start of the week.

Server Deployments

There are no scheduled deployment for week #34.

SL Viewer

No changes since my last SL project update, leaving the current official viewer list as:

  • Current Release version 4.0.7.318301, dated August 8th promoted August 11th – formerly the Maintenance RC viewer
  • Release Candidate viewers (refer to my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself):
    • Visual Outfit Browser RC viewer, version 4.0.8.318686, dated August 17th – ability to preview images of outfits in the Appearance floater
    • VLC Media Plugin RC viewer, version 4.1.1.318504, dated August 15th – replaces the QuickTime media plugin for the Windows version of the viewer with one based on LibVLC
  • Project viewers:
    • Project Bento (avatar skeleton extensions), version 5.0.0.317597, dated July 14th – incorporation of final skeleton and slider updates from the test viewer
  • Obsolete platform viewer version 3.7.28.300847, dated May 8, 2015 – provided for users on Windows XP and OS X versions below 10.7.

SL Wiki

As noted under a separate article, the SL wiki is currently locked from public editing due to spamming issues. There is currently no ETA on when it will be made generally available for access. Those with a definite need to have edit rights should raise a support ticket requesting access.

2016 SL project updates 33 (2): server, viewer, Bento update 23

West of the Rain; Inara Pey, August 2016, on Flickr West Of The Rainblog post

My apologies for the latest of this update. Working on my recent Sansar Summary pushed this update completely out of my mind!

Server Deployments – Recap

There were no deployments to the Main (SLS) channel or the RC channels this week. It is currently “doubtful” there will be an RC deployment next week – although this may change. A contributing reason for the slowdown is that the Lab is currently focused on server-side operating system upgrades.

SL Viewer

The Visual Outfits Browser RC viewer updated on August 17th. Version 4.0.8.318686 sees the viewer merged to the current release viewer code, and the following additional updates:

  • A fix for Outfit Gallery failing to use local files Select Photo Picker
  • A fix for Snapshot preview being corrupted
  • A fix for a crash in the viewer when using the snapshot preview.

All other official viewers remain as per my Current Viewer Release List.

Project Bento

The following notes were taken from the weekly Bento User Group meeting, held on Thursday, August 18th at 13:00 SLT at the the Hippotropolis Campfire Circle. For details on the meeting agenda, please refer to the Bento User Group wiki page. No audio is supplied, as the meeting was fairly short and sharp, without a major amount of discussion.

SLM Files

SLM files are produced alongside of the Mesh .DAE files. They can be a problem as by default, the official viewer is set to check for any existing SLM file when uploading a mesh model, and this can lead to confusion when trying to fix issues by overwriting the original .DAE, only to have the viewer reference the existing SLM file, either causing problems on upload or giving the impression the issues in the model haven’t actually been fixed.

Firestorm has always avoided this by having the debug setting MeshImportUseSLM set to FALSE by default, and the suggestion going forward is for the official viewer to do them same.

Mesh Distortions with Altitude

The issue of facial distortions with altitude when software skinning is used continues to prove difficult to resolve. The general recommendation is to use hardware skinning (my Bento Update #19). The root cause of the problem appears to be a floating point error which can affect any mesh. The Lab is still looking at it, but given there is a workaround by using hardware skinning, the problem is not seen as a major blocker.

Proposals for NOT Having Mesh Influenced by Sliders

There have been requests to not have the avatar bones influenced by the shape sliders (i.e. by a creator optionally locking both the scale and position of a joint). The Lab is looking at this, but if any work is done, it will not be prior to the Bento viewer reaching release candidate status. Whether anything may be done was the RC version of the viewer progresses towards release (the work is not seen as a huge amount of effort), or whether it is a piece of “post-Bento” work is still to be decided.

Avatar Test Files

Cathy foil has now updated the Maya male and female avatar models on the Bento Test wiki page so they match the latest Bento skeleton updates (as of August 17th, 2016). Then both utilise the same (female) skeleton, the male version have a male mesh / morphs applied. Cathy has used the Avatar Bento angel weights and apply them to the models, so the faces and fingers are all fully rigged, although both are sans wings and tails.

Cathy will be making a set of .FBX files of the models, which will also be placed on the Bento Test page when available, for those who are not using tools such as 3D Studio Max for their work.

Elizabeth Jarvinen (polysail) is also working on a tool for 3D Studio. Max which is intended to provide a second means of producing animations / meshes etc that isn’t reliant upon Blender / Avastar. However, this requires a considerable amount of work, not least in providing slider support, and Elizabeth has received offers of assistance from Vir and Cathy, who will also see about having the AvaStar team lend assistance.

Rigs Modifying Collision Volumes

As noted in my Bento update #22, recent reports of people encountering problems with Bento rigs which modify collision volumes (see here for details). As noted in that  update, this was not something that the Lab planned on supporting, particularly as it did not come up during the initial Bento development meetings with creators.

However, and as further indicated in my update #22 (with thanks to Whirly Fizzle), an update will be included in the next project viewer release for Bento which should hopefully fix the issues being encountered.

Release Progress

There has been a lot of questioning over the Bento release time frames recently, both within the Bento user group meetings and elsewhere (e.g. at TPVD meetings). Currently the plan is to get a further project viewer released in the near-term (possibly before the end of August), and then progress to release candidate status from there.

However, time frames beyond that become nebulous, because the Bento viewer, as a release candidate, will be vying for release alongside other RC viewers, some of which may have a higher priority, some of which may need to be issued in sequence, or have other pressures, and so predicting a date when Bento will be the de facto release viewer is difficult to predict.

This is further exacerbated by the fact the recent changes and requirements have required extensive updates to  AvaStar, much of which is still work-in-progress (see my Bento updates #22 and #21 for more). Once completed, this work will require further testing in order to confirm any problems within AvaStar are resolved, and any remaining issues (if uncovered) are viewer related, rather than external tools related. Then over and above this, there is the list of existing Bento issues which needs to be worked through, depending on the severity of the problems reported.

That said, it would appear the overall hope is to get Bento formally released before the end of 2016.

No Server Deployments

There was no deployment to the Main (SLS) channel on Tuesday, August 16th, and there will be no deployment on Wednesday, August 17th.

It is currently “doubtful” there will be an RC deployment next week – although this may change. A contributing reason for the slowdown is that the Lab is currently focused on server-side operating system upgrades.

2016 SL project updates 32 (2): TPVD meeting

Eclectica – Mysticablog post

The majority of the notes in this update are taken from the TPV Developer meeting held on Friday, August 12th. The video of that meeting is embedded at the end of this update, and references to it are indicated through the use of time stamps in the paragraphs below. My thanks as always to North for recording and providing it.

Server Deployment – Recap

There was only a Main (SLS) channel deployment this week. This saw the roll of the server maintenance package previously deployed to the three RC’s in week #31, on Tuesday, August 9th. This comprised internal fixes and an update to prevent BUG-37573.

SL Viewer

Release Viewer – Texture Handling Fixes

[0:35] The Maintenance RC viewer release on Monday, August 8th gained a rapid promotion to the de facto release viewer on Thursday, August 11th. Version 4.0.7.318301 (dated August 8th).

This viewer includes a number of fixes in the image pipeline (e.g. fixes for “bad” textures – those texture files which have invalid data in them). Also included is a fix to prevent the viewer crashing when you system runs out of main (not GPU) memory while  attempting to load a texture file. Instead, the viewer will substitute a plain grey texture. So, when you start to see grey everywhere instead of expected textures, it’s time to restart the viewer. This may be a pain to look at, but it is considered preferable to having the viewer crash at a potentially inconvenient moment.

[1:35] The Lab intends to move along similar lines for other issues within the viewer which can result in a hard crash, and also go through cleaning-up how exceptions are generated and caught by the viewer, and this work should be appearing in the next but one Maintenance RC update. The overall goal is to improve the image pipeline and some other points in the viewer where a relatively low-level thing results in the viewer crashing. Some of this work might also help prevent attempts to deliberately crash other viewers using textures.

In the meantime, issues have emerged affecting attachments and the Current Outfit Folder with this release – see BUG-37646 “Attachments get ghosted at login on 4.0.7.318301”; and BUG-37653 “Every time I delete Cache and Relog, my Saved Appearances do not load and I am left as a White Cloud in Second Life Viewer 4.0.7.318301”, for details.

Remaining Viewers in the Release Channel

[4:20] The VLC Media Plugin RC viewer, version 4.1.1.318152 dated July 28th at the time of writing, which contains the LibVLC-based replacement for QuickTime for Windows, is liable to be the next RC that will be promoted to release status.  A new RC version of this viewer, merged-up to the 4.0.7.318301 code, should appear in the release pipeline in week #33 (commencing Monday, August 15th).

[4:32] The plan remains to update the Mac version of the viewer to use VLC as a part of the 64-bit viewer development.

[6:10] The Visual Outfits Browser RC viewer, version 4.0.7.318263 dated August 1st at the time of writing, which allows users to preview images of outfits in the Appearance floater should be updated in week #33 following a merge with the 4.0.7.318301 code. This update will also include a further round of bug fixes for this project.

Project Bento

[7:35] A new project viewer is being readied, which includes bug fixes and which has been merged with the 4.0.7.318301 code. This should hopefully appear in week #33. See my Bento update 22 for more on the project.

Upcoming Viewers

[6:43] A new Maintenance viewer should appear in week #33. This will contain further fixes and improvements, although not the exception handling improvements referred to above.

[7:00] Work is expected to resume on the 64-bit versions of the official viewer in week #33.

SL Voice

[9:45] Work is progressing on Voice, with a further SL Voice plugin update expected from Vivox soon. Oz has been debugging an upcoming project / RC viewer with more Voice fixes – although this isn’t yet ready to be issued.

Avatar Complexity

It has been noted that Avatar Complexity values can fluctuate when seen from different systems, on average by around 5%. This is because it is next to impossible to come up with a single figure that s accurate across all systems, as the calculations have a degree of hardware dependency (GPU, rendering capabilities, etc),

However, the Lab will continue to tweak the calculations to try to make them as consistent as possible, but this will be a gradual process for reasons Oz discussed in the meeting, and which I’ve extracted in the audio file below

A couple of particular issues which have been reported for avatar complexity calculations are BUG-37631 “Rigged mesh with partially transparent texture on it have 4 times higher complexity”, and BUG-37642 “ACI randomly changes (often at login or following a TP)”.

Other Items

Memory Bloat Crashers

[8:50] With the arrival of Avatar Complexity, which provides protection against worn graphics crashers (just don’t set your Maximum Complexity slider to No Limit), it appears that inconsiderates in the virtual world are swapping to use attachments which cause memory bloat in order to crash viewers. There are, for example, attachments which can raise viewer memory to 4 Gb which immediately crasher 32-bit viewers, even if the offending avataris “Jelly Dolled”.

Oz has requested the Lab be supplied with examples, so they can start looking into the matter and hopefully come up with a fix.

Abuse Report Categories

[10:31] One of the possible issues for some Abuse Reports (ARs) appearing to go unanswered is that there are still viewers using the “old” AR categories, rather than the newer categories (as found in the official viewer). This is particularly true where users are still on versions of the viewer which do not have the revised list of AR categories.

To prevent this is the future, the Lab plan to make Abuse Report categories a capability handled by the simulator and downloaded to the viewer. This removes storing the categories in the viewer & having older viewer fail to reflect more recent category updates. It will also make it easier for the Lab to update AR categories to better meet users’ needs. A project viewer will be appearing at some point in the future supporting this new capability.

Also, within the official viewer, appending a snapshot to an AR is to become mandatory, rather than optional, to further help support identify issues and deal with them. Having a picture may not be relevant for all ARs, but for those where it could help in identifying issues, it ensures the picture is provided, rather than ignored.

Project Bento User Group update 22 with audio

Project Bento – extending the SL avatar skeleton

Updated: animation of collision volumes is being added – section updated section below.

The following notes and audio were taken from the weekly Bento User Group meeting, held on Thursday, August 11th at 13:00 SLT at the the Hippotropolis Campfire Circle. For details on the meeting agenda, please refer to the Bento User Group wiki page.

Note that this update is not intended to offer a full transcript of the meeting, nor does it present the discussion points in chronological order. Rather, it represents the core points of discussion, grouped together by subject matter were relevant / possible, whilst maintaining the overall context of the meeting.

Time Frame for Promotion to Release Candidate Status

Some at the Lab are keen to see Bento move forward and reach a larger audience of content creators (although there is currently no reason why creators cannot get involved now and attend meetings, help with feedback, etc). Inevitably, this means promoting the Bento viewer to release candidate status, and doing so some time in the next two weeks has been mooted.

Given the number of issues currently being investigated, not all of which are viewer-specific (see below), but for which fixes may yet have an impact on the viewer, this would seem to be a somewhat ambitious time frame.

Viewer Issues

Work at the Lab is focusing on a batch of issues for which bug reports have been raised, including:

  • Several relating to joint positions:
    • BUG-37546 [BENTO] facial bone joint offset issues – which has been the subject of recent Bento updates in this blog
    • BUG-37591 [BENTO] New import of a non-human rigged mesh is deformed
    • BUG-37633 Bento – Custom joint positions and Reset Skeleton not matching
  • Avatar height calculation issues:
    • BUG-20013 [Bento] When wearing a Bento avatar, observers see your hover height lower than you see it yourself
    • BUG-20169 [ BENTO ] Z-Offset not applying correctly & camera tied to Z-offset
  • Eye scaling problems (referenced via SL-433, an LL internal bug report)

The eye scaling issue, the result of the scaling within the viewer for mesh eyes being different to the expected system eye size, has been corrected, and will be one of the fixes released with the next viewer update, although existing models may need tweaking as a result a test carried out during the meeting using an early build of the next project viewer iteration suggested that there are still issues, and Matrice believes part of the problem might be within AvaStar.

Facial Bones Issues / Distortions

At least some of the facial bones issues appear to lie with AvaStar exports, which Matrice and Gaia are trying to rectify. Gaia offers an explanation for the problem in the Bento forum thread. Matrice further notes that there is a discrepancy between the restpose and the SL default pose; in Blender there is no easy way to define the absolute SL restpose in order to add bind pose information on top of it, leading to the wrong information (or even a lack of information) being exported to the Collada files.

Matrice is working on improving things in AvaStar, but the work is taking time and effort. Gaia has offered a detailed explanation of joint preparation on the Machinimatrix website as a workaround as they continue to redefine and improve their workflow, and offers a brief summary of the approach through the forum thread. The workaround isn’t seen as optimal at the moment, but the hope is that once the work on AvatStar has been completed, the workflow should be more straightforward and transparent.

Machinimatrix have produced a workflow process to handle the correct placement of facial bones. This is not intended to be the finished means of doing so, but is offered to counter issues currently being encountered

Some questions were asked on whether it was an AvaStar issue rather than something inherent in the viewer, prompting Vir to comment that given the viewer handles joint positions in a model and joint positions in an animation pretty similarly, it’s hard to see how the viewer could be at fault, but acknowledged the only way to be sure of this is test once AvaStar have reasonable confidence they have corrected the issues they have identified.

Later in the meeting, Matrice offered a further explanation of the Belender / AvaStar issue,  also pointing to the explanatory document on joint preparation, again noting that things are very much a work-in-progress on trying to fix things.

During the meeting, Medhue Simoni tried the recommended approach given in the documentation and found it did resolve all of his facial deformation issues, other than with his eyes, which as noted above, may require further viewer-side tweaks and additional work within AvaStar, as Matrice commented.

Avatar Height Position Issues

I’ve covered this at length in past updates (see update #21 and update #19 for more). The Lab hasn’t progressed any further with a fix, but may look to alter the frequency of updates to see if this helps.

The problem is viewed as being rooted in animating one of the bones used in the calculations for determining the avatar’s height relative to the ground (left leg, up through the pelvis and head), so the solution may ultimately be down to alternative means of animating movement without touching something like the pelvis bone – something which may not be possible when trying to replica certain types of natural movement.

Rigs Modifying Collision Volumes

There have been recent reports of people encountering problems with Bento rigs which modify collision volumes. As Vir explains in the meeting, it’s not something that the Lab planned on supporting, nor did it come up during the original Bento development meetings when rigging to attachment points was discussed, so no effort has been put into making sure it works at all. Vir is now looking at the issue, but whether the Lab will support it is questionable at this point in time; however, the focus at the moment is to more fully understand the impact.

Update, August 12th: Whirly Fizzle pointed me to a viewer repository containing an update to support the animation of collision volumes, to avoid breaking existing content.

Other Items

Slider / Bone Spreadsheet

Aki Shichiroji has been putting together a spreadsheet of all the slider settings and how they affect the Bento avatar bones and geometry. It is very much a work in progress, given things are still in a state of flux, and Aki notes she is aware that there is missing information (she has yet to run through the avatar.LAD file and the avatar skeleton file). However. she has made the spreadsheet available through Google Docs, and welcomes constructive feedback from content creators (which should be addressed to her, I’m not sure if Aki reads this blog!).

Maya / MyaStar And Custom Joint Positions

Following the discussion of Blender / AvaStar and custom joints, Cathy Foil provided some additional information to help Maya users with MayaStar.
