What dreams may come: Kirstenlee further updates S19

Posted on by Inara Pey

kirstensKirstenlee Cinquetti has issued a further update to the S19 version of Kirsten’s Viewer – version S19 1.19.4 (407). Released on Thursday May 16th, 2013, the update primarily fixes a nasty cache crash when user settings and local cache are manually deleted.

There have been a lot of questions as to why the S19 (v1-style) viewer from Kirsten’s stable is being updates rather than the S22/S23 viewers. In a blog post accompanying the release, Kirsten/Lee gives an answer:

So I guess the most pertinent question is why? It is probably the most pointless one to answer also.

But lets just take a wild stab at it!

I need to be in SL occasionally so I need a viewer (Duh), V2 is dead sorry S22 it was fun, V3 is well lets just say it’s not my cup of tea. I could just download someone else’s viewer but thats not what I want.

I LIKE S19 it was and still is quick, its code in comparison to newer clients is simpler it has much more modest hardware demands I can merge from many sources more rapidly etc, etc, etc..
It ticks all my boxes, on a more personal note it’s NOT limited to Second Life.

That is important to me, so it may have bugs, it may not compile on macs very well… sorry.

But if I wish to drift around SL or jump into Opensim I can.. anyway hope that kinda answers some of my motivations, and why I share the corresponding installer.

As mentioned in my last piece marking the “return” of the S19 viewer, and people shouldn’t anticipate routine updates and improvements; as Lee indicates in his bog post, this viewer has been updated and is being tweaked purely to suit his needs – and rightly so.

A couple of notable changes have been made since version S19.1.19.4.(404), the last version I used. Preferences have been moved from their “traditional” location in the File menu to appear under the S19 menu, and Depth of Field (DoF) has been added to the Graphics tab, in a dedicated sub-tab.

DoF is back!
DoF is back!

Sadly for me, I’m unable to test DoF, as deferred will not run on my hardware set-up, no matter how I fiddle with AA (which was Lee’s suggestion to me after I’d encountered problems with the 404 build). But then, as I noted last time, while I’ve always like Kirsten’s Viewer, my hardware has tended to sulk badly when using it.

However, for those of you missing Kirsten’s Viewer, here’s yet another update for you! Going on feedback following my original piece on S19’s return (in comments, IMs and DMs), it’s good to know the viewer still has loyal fans!

SL projects update week 20 (1): server, JSON, viewer release process

Posted on by Inara Pey

Server Deployments – Week 20

As always, please refer to the release forum  thread on the weekly deployments for the latest updates and discussions.

Second Life Server (Main channel)

On Tuesday May 14th, the Main channel received the Experience Keys project which is widely regarded (and referred to by LL staff) as the “experience permissions”. This means the project is now available across the grid, although there are no visible changes to be seen at this point. Release notes.

Speculation is still running high on exactly what the new project is – and whether it is “just” the experience permissions to partner the existing advanced creation tools ot something more – as well as whether the capabilities will be available for use across the grid (i.e. on Mainland as well as private estates). Details will be forthcoming from the Lab in time; for the moment, they’re holding their cards close to their collective chest.

Release Candidate (RC) Channels – JSON Capabilities

On Wednesday May 15th, all three RC channels should receive a new server maintenance project (release notes (Bluesteel)).  The project is designed to fix two crash modes and two bugs, namely:

  • A fix for ‘Overriding “Sitting on Ground” animation while sitting on the ground makes “stand up” button disappear’ (BUG-2424)
  • A fix for ‘ApplyImpulse now works only in the root prim’ (SVC-8227)

In addition, this project introduces new LSL support creating and parsing for JSON-formatted strings. The new LSL functions comprise: 

  • list llJson2List(string json) – converts the top level of the json string to a list.
  • string llList2Json(string type, list values) – 
    • Type is JSON_ARRAY or JSON_OBJECT
    • Converts either a strided list of key:value pairs to a JSON_OBJECT or a list of values to a JSON_ARRAY
  • string llJsonGetValue(string json, list specifiers) – gets the value indicated by spcifiers from the json string.
  • string llJsonSetValue(string json, list specifiers, string value) – returns a new json string that is the json given with the value indicated by specifiers set to value
  • string llJsonValueType(string json, list specifiers) – returns the type constant for the value in json indicated by specifiers.

At the time of writing, the RC deployments still had a question mark over them as testing was, according to Simon Linden when speaking at the Simulator User Group, “down to the wire, although it all looks good.”

Further information on the new LSL support for JSON can be found on the LSL JSON wiki page.

The project is being lead by Kelly Linden who described the reason for implementing them as being because he’s “keen on improving the ability to interface LSL with the larger web. The previous maintenance version expanded the content-type support of http-in and http-out which ties in with this.”

It is likely that further LSL support for JSON will be added in the future.

SL Viewer

Beta Viewer and the Viewer Release Process

A further beta viewer release was made on May 11th (3.5.2.275565) – see the release notes for details – in preparation for the deployment of the new viewer release process. The beta 3.5.2 viewer incorporates changes required by the new service.

While at the Open-source Dev meeting on Monday May 13th, I asked Oz Linden on the status of the new process. “Internally, we’re essentially already using it in that all projects are based on viewer-release,” he replied. “We’re starting system test of the server-side infrastructure changes this week… once those are tested, it’s just a matter of deploying them and we can fully switch over to the new process. ‘just deploying’ on our scale is always an understatement, incidentally.”

This does not mean the release process is about to be deployed, however. The server-side infrastructure testing is liable to be on-going for a while. One aspect which the Lab will be checking carefully is the changes made to the log-in process.

When a user logs-in to Second Life using an official viewer, a check is carried out to see if a mandatory upgrade is required. To prepare for the new release process, is check has been updated. “that’s not something one deploys without having taken every step one can think of to quadruple-check just a bit,” Oz explained.

How long the tests will take to complete is unclear, but it is unlikely the new release process will be deployed in week 20.

Materials Processing

May 8th saw the The materials project viewer updated with the release of version 3.5.2.275470, with the release notes available here.

Detail on the hint of a Katana created entirely using the new materials capability. The sword is made by June Dion and has an LI of 7

Work is continuing with the viewer, focusing on the UI issues which need to be resolved in order for the code to progress towards mainstream  release.

Server-side Baking / Appearance: key questions answered by the Lab

Posted on by Inara Pey

On Monday May 13th 2013, Troy and Nyx Linden appeared on a segment of Designing Worlds to discuss Server-side Baking / Appearance (SSB/A), alongside Brooke and Oz Linden, who were there to discuss Materials Processing.

Troy Linden is a Senior Producer at Linden Lab, who has been working on high-level server-side baking, and Nyx Linden is a Senior Software Engineer at the Lab, who has been working with the technical aspects of SSB/A and has been very much the public face of the project. Together, they answered a series of questions on the project put to them on behalf of users (the questions having been requested in advance of the show being recorded) by the Designing Worlds hosts, Saffia Widdershins and Elrik Merlin.

The following is a summary of the questions asked and answers given.

Nyx Linden (l) and Troy Linden (r) on Designing Worlds

Saffia Widdershins (SW): Let’s start with the basics: what is baking, and how is it being handled now?

Troy Linden (TL): Baking is a process where we take all the information that involves your avatar – how it looks – and we combine it to deliver a finished avatar. Currently, how it’s handled right now [is] your computer, the individual’s computer, handles all of the processing involved in determining your avatar’s appearance, and it sends all the result back to our servers. So it’s a pretty involved process and there’s a bunch of time that it takes to do all that.

SW: So how is that going to be changed in the future … and will it simplify it?

TL: Server-side baking is our new system. It’s where we actually stand up a new service that will handle all of the baking process on our end. And what this actually does is it takes the load away from your computer, the individual user’s computer, and the results are a faster, more consistent experience during the whole baking process in Second Life.

Elrik Merlin (EM): Just to be clear about this … in the new system, what will be handled by the server and what will be handled by the viewer, exactly?

TL: The new viewer will be sending the server and [be] the recipient of all the avatar data, while the server does all the calculations required. So your viewer will download the results [of the baking process] over a lot faster HTTP connection.

EM: So that’s the basics of how it works, so to speak; how would you summarise the benefits to users?

TL: Well, simply put, it’s a much faster, more reliable avatar rendering experience. So hopefully you’ll see less avatars being stuck in their clouded state as well as being stuck untextured. So they’ll actually appear the way the user actually intended much quicker.

SW: So it will be an end to that problem where you half-rez but, (laughs) your make-up is blurred so you look as though you’ve been having a really heavy night!

TL: (Laughing) That’s the plan. We’re actually seeing some great results so far, so we’re very excited.

SW: Are there likely to be any downsides? There will be less impact on peoples’ machines, is that what you’re saying, or could there me more?

Nyx Linden (NL): The one downside to the new system is, because it is such a big change from how we have done things in the past, everyone is going to have to update their viewer. It will be a mandatory update. Users who don’t update will start to see even more avatars fail to load. Fortunately, we have the viewer that people need to download released, and users who use any actively maintained third-party viewer should be able to download an update presently as well. As long as users do update, they won’t see any downsides.

EM: This is obviously nearing completion and we’re nearing implementation. Can you tell us a little about where the project is, what its current status is, and what the time scales are for introduction are going to be?

NL: Absolutely! So, we’re in a multi-stage release; at this point we have our first viewer out the door. So the next stage is that we’re going to be standing-up the service that is going to be doing all the work for rezzing your avatar. Over time we will slowly roll-out the new system across the grid. That’s going to take some time, and we’re going to be following-up through our blogs and forums to let people know how that process is going, but we want to take our time with that process, to make sure that everything is working as well as we think it is.

Restrained Love Viewer updated

Posted on by Inara Pey

Update: May 13th: The Linux version of RLV was updated by Kitttin Ninetails to version 2.8.4.1 on Sunday May 12th, and is available here.

On Friday May 10th, 2013, Marine Kelley released the latest version of her standalone version of the Restrained Love Viewer (RLV) for Windows – RLV 2.8.4.1. The release is the first update to RLV in 2013, and is based on LL’s 3.5.2 viewer code (3.5.2.264760, dated April 21st, 2013). As such, it brings RLV pretty much up-to-date with the majority of LL’s viewer-side updates and fixes.

Note that this article only applies to RLV for Windows, as supplied by Marine Kelley. The Linux and Mac versions supplied by Kittin Ninetails remain at version 2.8.3.5.

Communications Hub User Interface

With this release, RLV now uses the Communications Hub User Interface (CHUI) and the standard means of managing chat and IMs, together with the majority of fixes and updates made to CHUI through recent development and beta updates.

RLV 2.8.4.1 includes CHUI for managing communications

Server-side Baking / Appearance

Despite no mention being made of it in the release notes, version 2.8.4.1 of RLV appears to also include viewer-side support for the upcoming deployment of Server-side Baking to the main grid.

To confirm this, as I was somewhat surprised that the release notes failed to make mention of any support, I dropped into the SSB/A test regions on Aditi to see how my avatar would render to others, and they would render to me when using the viewer. With the aid of my Crash Test Alt, all appeared to be fine.

Server-side baking: my avatar and Crash Test Alt as seen through RLV 2.8.4.1 (l) and through another SSB-capable viewer (r). Both render correctly; no greying or ghosting

I also didn’t encounter any issues in changing / re-ordering outfits which others have reported as encountering recently (although I admittedly have  – perhaps fortunately – yet to encounter any issues of this type while using any SSB/A-enabled viewer).

Other Updates and Fixes

Marine provides a list of additional updates and fixes:

Changes:

  • Camera focus is no longer lost when clicking on an in-world object. To change camera focus, right-click on your avatar, press Escape or focus on something else
  • Viewer allows moving an item or a folder from a locked folder to another locked folder (prevent only from locked to unlocked and from unlocked to locked)
  • Viewer does not expect the user to press Enter before chatting while in Mouselook, since they don’t have to when in 3rd person view
  • Viewer does not automatically rename folders or items in the inventory unless “RestrainedLoveAutomaticRenameItems” is set to TRUE (it is FALSE by default). This is no longer necessary since the viewer no longer needs to figure out whether or not it will kick a locked object because it now Adds by default now.

Fixed:

  • It is no longer possible to drag and drop an item from an object in-world directly into  inventory, regardless of RLV attach restrictions
  • It is no longer possible to wear rezzed items by right-clicking on them in-world and selecting “attach to”, even when @unsharedwear was active
  • It is now possible to hide the UI when unable to rez
  • It is no longer possible to create new pieces of clothing regardless of RLV outfit restrictions
  • The Control key wouldn’t work in Mouselook. Fixing this removes the ability to control the speed of the mouse view while holding Control, but Shift already does something similar.

SL projects update 19 (3): server, pathfinding, materials & more

Posted on by Inara Pey

Server Deployments – Week 19

The week 19 server deployments went ahead as scheduled and as outlined in an earlier part of this report, to wit:

SLS (Main) Channel

On Tuesday May 7th, the Main channel received the maintenance package which has been running on Magnum. This project brings some new minor features to LSL, and fixes some crash modes and well as additional LSL HTTP support, as well as the previously rolled-back new AO capabilities.

In addition, this package included an additional update which was not documented in the release notes until after the deployment had been made: “Fixed a bug: ‘Orientation data for landing point is disregarded during teleport’.

This fix means that when teleporting to a place which has a defined landing point, you will arrive facing the direct determined by that landing point, rather than arbitrarily facing east. To complement this fix, there is an upcoming viewer update which will show the heading of a parcel’s landing point on the map – but no details on when that update is liable to appear.

Pointing out the fix at the Server Beta meeting, Maestro Linden added, “There’s an exception for cases in which if you have a beacon set, where you’ll face the beacon position instead. I think this is a bug.”

This lead to a discussion on the exception, in which the wider consensus appeared to be that having an avatar facing the beacon (when set) on arrival might be the preferable to automatically having the avatar facing the direction imposed by the landing point. However, this would mean people using a beacon would arrive at the landing point facing a direction other than the land owner intended, prompting Voidpointer Linden to comment, “Yeah, seems like we would only want to have you face the beacon when going to a landing point if it’s in the same region, maybe?”

It’s currently unclear as to whether the feedback from the meeting will mean this exception is allowed to continue, or whether there will be further tweaking with the landing point code in the future,

Release Candidate Channels

On Wednesday May 8th, all three Release Candidate channels (BlueSteel, LeTigre and Magnum) received server-side support for experience permissions which was running on BlueSteel in week 18. The update, as usual, will also include the changes which are going to the Main channel on May 7th, which included the new AO capabilities – release notes (BlueSteel).

SL Viewer Updates

Beta Viewer

The beta viewer as we currently know it received what might by its final update prior to the new viewer release processing coming into effect. Version 3.5.2.275565 was released on May 9th, and the release notes provide details on changes.

Materials Processing Project Viewer

A new version of the Materials Processing viewer – 3.5.2.275470 – was released on May 8th, based on the 3.5.2 viewer code. The release also appears to include a fix for MATBUG-38 (“Material with normal map but no specular map is always specular with no adjustment possible”), and which I’d described in week 18.

MATBUG-38. appears to have been fixed in Material Processing project viewer 3.5.2
MATBUG-38. appears to have been fixed in Material Processing project viewer 3.5.2.275470, May 8th 2013.

The release may also include a fix for MATBUG-16 (Changing one material, or setting causes another material texture to be lost), which I’d previously noted in week 16.

Whether this latter issue is fixed is hard to judge, as it was somewhat intermittent to start with. and there have been reports that it was already less noticeable with the previous release of the viewer. However, at the time of writing, the bugs remain marked as Unresolved / Incomplete in the public JIRA (but could have been updated in LL’s internal JIRA).

I can say that I’ve so far been unable to reproduce either bug using the new release, having carried out a number of individual tests.
