Second Life – How to Lower ACI – A Script

One of the complications in 3D rendering is working out how to blend the objects with transparent parts. Think of windows and SL hair. Designers can reduce the complication by how they use alpha layers and blending. I’m not going to try to explain how to set stuff up because I have yet to get it figured out. But, I came across a handy workaround for things we already have.

I buy hair, dresses, and other things that use blending modes. Most are no-mod. But, the script below can be used to modify them.

In the beginning of the video, I am wearing Magika’s Dreamy as purchased. This is hair that in the Linden viewer has an ACI of 4,699. Using the script reduces the ACI by 702. That is a saving of 15±%. This is my first try, so I have no idea if this is typical, minimal, or a max. You may find that high ACI items benefit more.

There is some degradation in the appearance. When zoomed out, it is barely noticeable. Only when zoomed in can you see the difference. Personally, the 702 ACI saving is not worth the loss of appearance. Continue reading

Second Life News 2016 w42b

Last week (41) Simon Linden told us about the new Sandboxes for the Premium members. I am just now getting around to writing that up. This week the new forced sit (llSitOnLink) for Advanced Experiences rolled to the main grid.

Premium Sandboxes

Premium members can now visit the “Sandbox Premium Weapons Testing” region. Plus, another group of regions is set up that runs all 4 groups of server packages. These are side-by-side, adjacent.

Simon says they are named, “Main Channel Sandbox A, Magnum Sandbox A, LeTigre Sandbox A, and BlueSteel Sandbox A. Those 4 I just listed are … they’re in a 2×2 square on the map.”  Continue reading

Second Life: Third Party Viewer UG 2016 w38

Oz Linden reviewed the status of viewer development. He pointed out that the Visual Outfit Browser (VOB) is now in the main release version of the Linden made SL Viewer.

They updated the VLC RC and Bento RC viewers with VOB.

Both RC viewers are doing well in the crash rate stats. Oz expects the VLC version to release to main viewer in week 39. That will leave the Bento RC as the only RC. Seems like the pipeline is emptying out…

Oz pointed out the Lab did block a few old viewer versions. Saying, ‘Only a few thousand users…’ would be affected. That number can sound bad. But, as a percent of SL users it is way small, likely way less than 1%.  Continue reading

How is Avatar Complexity Doing?

More and more viewers are adopting the latest Linden additions to the viewer. The RLViewer just added the Avatar Complexity feature. So, more and more people are noticing the pop up messages generated by the Avatar Complexity feature. Merchants are starting to respond to the feature also. I suspect for now that concern is anticipatory rather than reactive.

Never Stop Dreaming.

Never Stop Dreaming

I have always suspected the majority of Second Life™ users have a level of concern about the amount of lag they add to the system and take some steps to reduce it. Of course most of us want to avoid lag. A few entitlement types put off on the Lab. But, I think that is a small percentage.  Continue reading

Second Life: Jelly Babies Grow Up

That little baby girl grew up into the cutest DOLL… that is sort of what has happened with Second Life™ Jelly Babies. Earlier I wrote about the name Jelly Babies being trademarked. So, the Lab is not going to use that term for muted avatars. And I certainly am not going to call muted avatars muted avatars… ugh. That give no one an intuitive sense of what is being talked about.

I follow Mesh Body Addicts, a blog by LilDaria resident, Daria for short, which is all about mesh bodies and clothes. Love it. Daria is using the term JellyDolls in place of the trademarked Jelly Babies, which I like. So, we may have a new name for them.  Continue reading

Are Second Life’s Jelly Babies Breaking SL?

As I have pointed out more people are talking about Jelly Babies and the coming RC Second Life Quick Graphics Viewer version 3.8.6.305942 movement toward being the main viewer. Of course some know what they are talking about and others don’t.

High or low ACI?

I think – Jelly babies will take over SL soon (AKA how linden lab is planning to break second life) – falls in the ‘doesn’t’ category. utilizator404, the author, believes the Lab is breaking SL by introducing the Avatar Complexity Information (ACI) feature. I disagree, but I can see how some may consider the appearance of Jelly Babies as a problem. The opinion that Jelly Babies breaks SL is as valid an opinion as any. I just don’t agree with it. So, I’ll rebut it.

In the article an assumption is expressed that the Lab is not fixing the root causes of lag; failure to optimize the viewer, not changing how the viewer uses video memory, failure to use all the features of new video cards, and no use of Direct3D (a Windows only graphics render engine).

Most of 2014 and 2015 has been spent optimizing features of the viewer and SL servers. If you follow Inara’s or my blog you already know that. If you have only read the release notes of the Linden and third party viewers as they are released,  you know that numerous fixes for how the viewer use memory have been made. From the Third Party Dev’s meeting we know more are in progress.

Second Life’s Render Complexity – Discussion Starting

We have been here before. A feature like the old Avatar Render Cost (ARC) was used by what became known as ARC Nazis to abuse people. You see a type of person that has basic authority issues, control issues, or a bullying nature adopt a fascist mentality and start telling people what they can do. Some in those groups start trying to enforce their will on others. Abuse, shame, hate, anger… and more is called into service in attempts to enforce their will on others.

Geisha Shadows

Geisha Shadows – Think this gorgeous outfit has a high ACI?
If it does, is that good or bad?

We could call this politics… In SL it is more often called drama. But, whichever we call it, it has the same source: human nature. Humans are different, unique. But, we all have the same basic traits, just in different degrees and we learn to cope with issues in different ways. We call the result character.  Continue reading
