SL project updates week 47/2: TPV Developer meeting

The following notes are drawn from the TPV Developer meeting held on Friday, November 21st, as shown in the video below, and from the Server Beta Meeting held on Thursday November 20th. Where relevant, timestamps are included in the article to allow for referencing to the video. My thanks as always to North for the recording.

SL Viewer

[01:10] RC and project viewers are starting to stack-up once more, and further viewers are on their way. The release channel currently has four RC viewers in it: HTTP Pipeline; Snowstorm; Maintenance, and Attachments

HTTP Pipeline RC and Texture and Mesh Fetching

The HTTP Pipeline viewer appears to be performing better with the CDN than the current pipeline code for those encountering problems. However, further updates to the RC are likely before it reaches a release status.

[05:23] In general, texture and mesh fetching via the CDN continues to work well for most people, although the Lab are still investigating why it is not working so well for some. The hope is that further improvements will be forthcoming, but at the moment the work is still very much in progress.

Attachments RC Viewer

[07:55] Vir Linden has some further updates for the Attachments RC, which should help improve the predictability of getting the right appearance as you’re going through outfit changes. This work has been tested in a closed test viewer and the results are such that Vir hopes to pull them into the RC version of the viewer as soon as possible.

Benchmark Viewer RC

[02:33] A new Benchmark viewer (removal of the GPU table) should hopefully be released on Monday, November 24th (or shortly thereafter). This includes:

  • Further improvements to how the viewer initials sets graphics preferences for some GPU types
  • Address the crash-on-start-up issue which some users are encountering in the current release viewer (, and which appears to be related to the benchmark update.

Those wishing to try a pre-RC release can do so by downloading from here.

Viewer Build Tools

[30:19] The Lab is making progress with compiling the viewer using the new build tool chains. The performance issues that resulted when building the Mac viewer (again, see my week 43 report), appear to have been resolved.

The work to build the windows version of the viewer using Visual Studio (VS) 2013 is going “really well”, with the Lab having almost all the packages ready to go – so much so that Oz believes that the Lab will have a version of the viewer built using VS2013 in week 48 (week commencing Monday, November 24th) – although this doesn’t necessarily mean said viewer will be publicly available.

As Microsoft have just issued Visual Studio Community 2013, which allows developers to create applications for free, so long as they are not intended for commercial gain (and TPVs aren’t built to be sold), it is hoped at TPV developers will in future be able to builder their viewers with exactly the same software as the Lab.

In addition, the Lab is working on an internal wiki page for building with VS2103, which will likely go public when finished to sit alongside the existing wiki page on the new autobuild process.

Viewer-managed Marketplace

The Viewer-managed Marketplace (VMM) project viewer, version, was released on Friday, November 21st, together with information on the open beta testing for VMM on Aditi. I have provided coverage of this via a separate article in this blog, see:Viewer-managed Marketplace: beta testing and a look at the project viewer.

Viewer-managed Marketplace: beta testing and a look at the project viewer

In October 2014, I reported on the viewer-managed Marketplace (VMM) project, which the lab has been developing for several months.

The aim of the project is to enable merchants to manage the creation and management of Marketplace product listing through the viewer, bypassing the need to use the Merchant Outbox (and have copies of items stored on the Marketplace inventory servers) or using Magic Boxes.

VMM does this by adding a new Marketplace Listing panel to to viewer, of which more below.

On Friday, November 21st, the Lab announced that wider beta testing of VMM is now ready to start on Aditi (the Beta grid). and is inviting merchants to download a new VMM project viewer they can use to test creating and managing product listing through the viewer.

Alongside of the announcement, the Lab also made available:

If you are a merchant and wish to test the VMM functionality, you’ll need to download and install the project viewer, and use one of the following three test regions on Aditi: ACME D; ACME E and ACME F. Using the viewer anywhere else can generate error messages when first logging-in (designed to indicate VMM is not available, and which will not interfere with using the viewer for other activities).

If you’ve never logged-into Aditi, please refer to the instructions on how to do so on the beta grid wiki page.

You may also wish to be logged-in to the Aditi Marketplace place.

When testing VMM, remember that it is not intended to enable all Marketplace-related activities through the viewer. Rather, it is intended to allow merchants to create new Marketplace listings with inventory, associate inventory with an existing Marketplace listing, remove items from a listing and unlist goods entirely. All other Marketplace activities will still have to be carried out within the Marketplace itself.

Also note that at present there is a bug within the Aditi Marketplace that will cause purchases to fail. The Lab is working to address this, and it shouldn’t interfere with testing VMM to create and modify product listings.

The following notes are intended to get you started with the project viewer and beta testing, please refer to the Lab’s VMM FAQ for other pertinent information.

The heart of the viewer-managed Marketplace is the new new Marketplace Listing panel within the viewer. This will eventually replace the Merchant Outbox,  although both are provided in the project viewer.

The Marketplace Listing panel allows a merchant to carry out a number of Marketplace tasks from within the viewer, such as:  create a new product listing, modify a listing, change the items associated with a listing, etc.

It does this by enabling merchants to directly associate products in their inventory with product item listings on the Marketplace, eliminating the need to either upload copies of products to the Marketplace inventory servers via the Merchant Outbox or, in the case of limited stock items that are No Copy for the merchant, having them stored in-world in a Magic Box. When a customer purchases an item listed via VMM, it is delivered to them directly from the Lab’s asset servers.

This does mean that care must be taken when handing product items in inventory in order to avoid occidentally deleting items associated with Marketplace listings. To help with this, the folder associated with the Marketplace Listing panel remain hidden from view (as far as is possible) when working directly in the inventory .

Google Form

The first time you open the Marketplace Listing panel, it may display the following message:

This feature is currently in beta. Please add you name to this Google form if you would like to participate

If this happens, it is likely because you logged-in to a non-VMM region and then teleported to the test regions. To correct, simply log-in directly to one of the three ACME test regions (ACME D; ACME E and ACME F). The Marketplace Listing panel should open correctly; if you haven’t already created an Aditi Marketplace store, it will display a message requesting you do so, with a link to the Marketplace.
