Second Life Mesh Meeting Update Week 26

by

Mesh cost is still an annoying topic of conversation. It is still undefined. But, we are getting closer to a cost and we are learning more about the reasons for the costs. The Lindens are definitely being more open about the Linden costs. That hasn’t done much to improve the manners of residents participating in the meetings. 🙁

Mesh Meeting

Mesh UUID Swapping

This subject keeps coming up. Kyrah Abattoir  asked the question in a new way. Quoting, “Figuring out a sane and conservative way to implement “set by UUID” for Meshes, builtin delay by link set for example, to prevent excessive mesh swapping/animating attempts, yet allow loading and unloading a mesh for legitimate uses. It seems to me this question assumes a swap can be done and that it is frequent swapping that overloads the sim. Originally many hoped that mesh could be animated as sculpties are.

Firefox 5 Released

by

I just saw a new Firefox browser is out, version 5. I started looking to see what is new in Firefox 5. The hype is 1,000’s if new things. The reality is; not much… from the users perspective. There are the ubiquitous bug fixes, plus new security measures and a few new features.

Firefox Twitter

Popularity

Internet Explorer has the largest number of users. However, that does not make it the most popular browser. As it is built into Windows, new and novice computer users have no clue that better browsers are available. Among intermediate and advanced computer users alternate viewers are popular. They actually make a choice as to which browser to use. So, while debatable it is Firefox that is the more popular browser. Behind it is Google Chrome, my favorite.

Work Around for Rigged Mesh

by

For those of us using Blender 2.5x the problem with rigged mesh not exporting correctly is a known issue. A couple of days ago Tapple Gao posted a fix for that problem in the SL Forum. See: Rigging working in Blender 2.5 This is a geeks only fix. The fix submitted to Blender.org is code that must … Read more

#SL and Scale

by

Or how tall are you? Really? There is a great post by Penny Patton in the SL Forum. See: A Matter of Scale – How scale affects content creation and land ownership in Second Life. Every builder should stop by and read the post. I doubt many people think this through before they build.  

#SecondLife Server Updates Week 24.5

by

The week of 6/12-18 there was not a main server roll out. The week of 6/19-25 we did get a roll out on the main grid. The roll out had the group chat fixes.

Group Chat

Group chat has been receiving attention. The Utility Servers were updated over a week ago. Now the region simulators are updated, a minor fix.

One of the Group Chat Problems found was the Utility Server for chat had to send chat messages to multiple people in a region. If ten people were in a region the server had to send ten copies of chat updates to the region. This change allows the utility server to send the sim one message and the simulator distributes the chat updates. This sim change is not something that makes a lot of difference to most users. But, any load taken off the utility servers running group chat helps.

The previous update to the utility servers has made a significant difference to group chat for everyone. Enough so that this alarming JIRA was filed: https://jira.secondlife.com/browse/SVC-7031

Group Chat Performance

The above image is a plot of chat messages (messages + group status updates) per minute sampled over one day. Each dot is one of the 16 utility nodes.

KirstenLee S21(8) RC3 Released

by

RC2 was out 6/9. RC3 fixes some of the problems with RC2. One change is this version of S21 is very stable. No crashes after hours of use. There is no typical announcement on KirstenLee’s blog. But, the new download link for the RC is on the home page.

Camera

There are some ‘camera’ issues that show up when one is trying to select objects for editing or for camera zooms. I’ve seen problems for some time in most series 2 viewers. But, this is far worse. A click to select something often selects the object behind it. Other times selecting an object launches the camera to some odd new position. Research is on going to see whasup with that.

Speed

I’m seeing some odd results on FPS (Frames per Second) rates. In my cottage or places with few avatars I get good FPS. In places with lots of avatars I drag down to 9 to 12 FPS. Even in a shopping mall with lots of textures but few avatars, I see good FPS, typically 15 to 25 FPS.

Some are seeing good FPS even when there are large numbers of avatars around. I may need to mess with my settings.
