Server Deployments Week 6

On Tuesday, February 3rd, the Main (SLS) channel received the server maintenance package deployed to the three RC channels in week #5, which includes:

  • a fix for BUG-8247 “[Experience Tools] Issue with llRequestExperiencePermissions() triggering experience_permissions_denied() and XP_ERROR_NOT_PERMITTED_LAND after prior 5 minute no response period.”
  • Internal improvements for experience tools key-value functions.

There were no deployments to the RC channels for the week.

Following the Main channel deployment on Tuesday, a number of regions reported issues with objects failing to load and render, textures remaining grey, mesh outfits failing to rez / render teleport issues, etc., all of which appeared to be consistent with region capabilities failing on re-start, and thus requiring the affected regions to be manually restarted. As reported by Whirly Fizzle in the forum thread linked-to above, this has been an intermittent problem which has been occurring for over a year.

SL Viewer – Mesh Importer Update

On Wednesday, February 4th saw the release of the Importer project viewer, version 3.7.25.298441. This viewer brings various improvements to the mesh uploader / importer, which are given in the release notes as:

In this viewer we’ve modified the importer to (optionally) improve debug output, perform name-based LOD association, and handle models with many materials.

Using these new features, models with more than 8 unique faces can be imported. Gone are the days of importing complicated meshes in pieces with “some assembly required”. At import, these models are automatically split into pieces so that each satisfy the current face limits for a volume.

  • The same limitations on LODs and materials remain in place (e.g. your low LOD mesh materials must be a subset of the full LOD materials).
  • LODs and Physics reps can now be explicitly associated with a given mesh in the full LOD model using name-based matching.
  • By properly naming the meshes in your lower LOD meshes and physics reps, you can avoid issues with ordering of the meshes within your DCC tool and other material mismatching errors.
  • An ImporterDebug option has been added to the settings.xml file which, if enabled, causes more information to be output during import than you can shake a stick at. The extra output can be very helpful for diagnosing authoring errors (e.g. violating the material subset constraints mentioned above) and pinpoint what needs to be fixed in the source model for successful import.

Note that project news is a little light this week due to on-going SL planning meetings taking place at the Lab.
