This Week in OpenSim Dev – week ending Saturday 21st August 2010 August 23, 2010

Posted by justincc in opensim, opensim-dev, opensim-news, secondlife, twiod, virtual-environments, virtual-worlds.

Hello everybody.  This is a summary of the last week of development in OpenSimulator.  Except where otherwise specified, the changes described here appear only in OpenSim’s cutting edge Git ‘master’ branch. Please do not attempt to use code taken directly from ‘master’ in any production environment.  Sometimes this in-development code may not work or may even cause data corruption. If you are not a developer or tester, please treat this summary instead as a preview of what will be coming up in the next release. The latest official release is OpenSim (released on Tuesday 10th August 2010).

The letters and numbers in brackets after some entries tell you the latest git commit to which they apply.

This week in OpenSim ( d3c2424 – 8d8436e ).

General news

  • None this week.

Features & bug fixes

  • I added extra textures to OpenSim’s built-in asset library to replace those no longer shipped with Linden Lab’s Viewer 2 and derivatives.  Linden Lab provides these under a license which allows them to be included in OpenSim.  Remaining problems for OpenSim compatibility with viewer 2 include (a) the inability to initially set the appearance on new avatars and (b) the world map always displaying Linden Lab’s own grid map.  One can work around the appearance issue by setting all body parts, pants and shirt with a Viewer 1.23 or derivative.  The world map issue can probably be resolved for Linden Lab Viewer 2.1 and later by sending a MapURL on login (this will require an OpenSim code change) (11db33d).
  • Melanie added some map tile generation options to OpenSim.ini.example.  This includes whether to generate them at all, how long to wait between refreshing them and which texture to show if no maptiles are being generated (ae554a4).
  • Melanie removed all use of the estate_settings.xml file.  Estate settings should now be changed via the facilities provided by the viewer (f445659).


  • Diva continued to work on improvements and bug fixes for Hypergrid 1.5.

Thanks for the update Justin 🙂

3. Ai Austin - August 23, 2010

Wonder why I am seeing my region map tiles fine in all viewers? Could it be the way some OpenSim.ini parameters are set?

4. justincc - August 24, 2010

@Ai – That is curious. Perhaps there is an existing parameter that can alter this. Needs more investigation.

5. Ai Austin - August 26, 2010

My fault.. I was using so many viewers and variants I got confuseed. It is the case that Viewer 2.x uses the Second Life maps and not the Opensim served ones.

hi Justin!~ =) thank you for the update as well as a big thank you to you and all the OpenSim developers!

for teh textures you upload into the library, what do you upload them as? like 512×512 png8s

i know textures are huge as far as impact and i continually strive to create efficient ones for my use, however, learning what you practice will likely impact what i do!

thank you

@Ener – I didn’t actually load the textures, they came from Nebadon 🙂

8. Ener Hax - September 2, 2010

Nebadon? is that like a galaxy, nebula, or distant planet? =D

*ener <– not one of the cool kidz*

9. justincc - September 3, 2010

@Ener – . Sorry Ener, I forgot that we don’t all live in the same bubbles.

Nebadon (Nebadon Izumi) is the virtual name of Michael Emory Cerquoni, a great guy who is president of OSGrid as well as a very long time OpenSim community member.

very cool, so he kind of is the galaxy since he is the president! and obviously likes textures! thanks! =)
