Update February 24th: Henri Beauchamp has filed a SUN JIRA on the Z-offset issue mentioned in comments following this article. Z-offset is an opton found in many TPVs which allows the vertical height at which an avatar stands / kneels / sits / lays to be adjusted through the viewer, allowing users to compensate for their avatars appearing to float in mid-air. The SSB code effectively “breaks” this capability. The JIRA description carries a comprehensive description of the issue for those unfamiliar with the problem.
Update, February 23rd: The Catznip team (which includes Kitty Barnett, have added a post to their blog on the subject of RLVa and SSB. Be sure to read it!
Following the recent Server-side Baking (SSB) pile-on / load test, I took a little time out to try-out the various viewer versions which are starting to appear which provide SSB support. This was not intended to be an extensive break test or anything – just something to sate my own curiosity on a number of points.
As such, the tests I conducted were simple, and as they were performed on Aditi, they may have been influenced by some of the inventory issues being experienced there. For the tests, I used my main account, and my CTA – Crash Test Alt, which routinely gets used when testing experimental viewers, etc.
Testing covered the Cool VL experimental branch, Singularity Alpha release with SSB support and Radegast 2.8. Throughout the tests, my CTA was running the official Sunshine (SSB) project viewer 220.127.116.110409. Testing did not include Lumiya, which has SSB support implemented. The reason for this is that I remain unable to log-in to Aditi with Lumiya.
I started with a couple of baseline tests to remind people of what is going to happen once SSB is deployed to the main grid.
Following this, I switched to using Singularity first and then Cool VL.Results wer as expected – both accurately rendered outfits and outfit updates without any significant issues.
Testing Radegast 2.8 also generated the expected results: outfits rendered correctly in both the Radegast 3D viewer, and in the SSB viewer, as did any outfit changes made via Radegast. Furthermore, and as expected, outfit changes made using one viewer were accurately reflected when logging into another viewer (so outfit changes made in Singularity were accurately rendered by Radegast, for example).The only issue I actually encountered was that footwear would not render correctly – which is not an SSB issue.
SSB and RLVa
While carrying out these tests, I also took a look at RLVa on SSB, and confess to not finding any obvious issues when using Singularity or Cool VL (which uses RLV). All RLV/RLVa options functioned as expected:
- Items “locked” as non-detachable remained undetachable until “unlocked”
- Restrictions applied through RLV/a all functioned as expected (e.g. map restrictions prevented access to the World or Mini-Map; inventory denial prevented inventory access, etc.)
- Remote access to #RLV Shared Folders worked as expected (i.e. remote changes of outfit worked and were accurately rendered)
- Remote (HUD-based) access between avatars worked as expected
- Control zone restrictions applied / released as anticipated.
This does not necessarily mean that RLVa is not “broken”. I actually have no idea if the Cool VL experimental or Singularity Alpha contain specific updates for RLV/RLVa outside of any work Kitty Barnett may be undertaking for RLVa and SSB.Aslo, just because the basic functionality of RLVa appears unaffected by SSB does not means that there are deeper, more subtle issues which need to be addressed in order to ensure all of RLVa continues to function correctly under SSB.
SSB is beginning to find its way into TPVs and appears to be working well – which is not to say that there are not bugs and issues still to be resolved with the service as a whole. Doubtless, we’ll find out more on this as LL continue to analyse the results of the initial pile-on test, and further tests are undertaken in the future. As a result of this quick-and-dirty play with the service over a number of viewers, I’m certainly curious to know if some of the issues encountered during the pile-on / load test (such as a noticeable slow-down in the time needed for outfits to render after a change) might be indicative that the system still needs tweaking in order to handle larger numbers of outfit changes, rather than all the problems being related to other issues on Aditi itself.
In terms of potential RLVa issues, I draw no conclusions; as mentioned above, the fact that the most obvious RLVa functions worked OK for me is not to say RLVa and SSB are without issues; there is much which goes on “under the hood” with RLVa which could very well be affected by the arrival of SSB which requires code refactoring but which does not result in outright / obvious breakages.
