Thoughts on Avatars & Anonymity.

August 8, 2014 in SL Thoughts by lokieliot

In the UK the topic of online anonymity is being discussed by a House of Lords Select Committee with the aim to curb online abuse from anonymous users.. 

For me, my avatar presents an interesting gradient to Identity vs anonymity. My SL avatar is my anonymity but also an identity, so its not really anonymity, but a pseudonym. But the way todays media seems to work Anonymity and Pseudonyms are merged and treated as the same thing sometimes as Google and Facebook seemed to do during the #nymwars.

I’ make quite an effort to keep My SL avatar identity separate from my real life, to the point of asking NWN’s to remove an image it posted of my real identity in order to disassociate my real life personal identity from my SL avatar in googleImage search.

There was a time when everything was tied together. I had Facebook, and Google whatever, building albums of videos and pictures of my family and friends and work. Then i reached a point where i didn’t want just anyone from anywhere looking at family pictures, seeing where i lived and what I got up to and where i worked. I was creating an environment thanks to growing social networks where anyone could comment on my personal life. If people wanted to bully or harass me then they could on Facebook, on my blog, or youtube. They could also easily find members of my family or friends, and i allowed this.

So i disconnected my real identity from my online world completely. Facebook, Google, Youtube, all social networks that took great pains to trawl my real world personal life  in order to create a history about me.

You give up finding out what people said they liked and instead you just look at what they’ve done in the past. You assembled all the data from people’s history – all the stuff they’ve looked at and bought in the past – and then compared that with other peoples’ past. Out of that came patterns and correlations that the human brain could not possibly see – but from those correlations you could tell what individuals would want in the future. Greg Linden was part of what was called The Personalization Group in Amazon. He said:

the joke in the group was that if the system were working perfectly, Amazon should just show you one book – which is the next book you are going to buy.

And it worked – sales soared, and Jeff Bezos who runs Amazon allegedly crawled up to Linden on his hands and knees saying “I am not worthy“.

What Amazon and many other companies began to do in the late 1990s was build up a giant world of the past on their computer servers. A historical universe that is constantly mined to find new ways of giving back to you today what you liked yesterday – with variations.

- NOW THEN – Adam Curtis - It’s an interesting article i suggest you read :)

So Social Networks won’t like me since i don’t give them any data about my real world for other companies to reference when trying to sell me stuff.

I’m left with my Second Life identity which is a pseudonym and become far more known around the world compared to my personal real world life. I’d be silly to bully or harass people online as my SL pseudonym because my avatar and SL name is incredibly valuable to me. Facebook are quite welcome to collect historical data on what i’m up to in virtual space, … actually no, they can fek off.

I’m somewhat surprised given that long time Users of Second Life curate their experience in virtual Space around their interests and hobbies, there is no evidence that Linden Lab have ever collected and used that historical data like Facebook. I wonder if Linden Lab have ever looked into it?

In May 2007, the then-chief operating officer of Second Life gave a “brown-bag lunch” address at the NSA explaining how his game (Second Life) gave the government “the opportunity to understand the motivation, context and consequent behaviours of non-Americans through observation, without leaving US soil”. – The Guardian.

I also wonder wether the Social Avatar in a virtual world is different enough from a text based social accounts that it could lead to a more valuable pseudonym if how 2ndGen VR enthusiasts are predicting the Web will turn 3D. But then i think about my friend who is on his 10 or 11th Alt account simply because he likes to try out new versions of himself but ends up just being the same instantly recognisable person.

The struggle between Anonymity and Identity is one of power and freedom. I should be free to explore any aspect of my life without being restrained by the capitalist and totalitarian need for everyone to be static and easy to predict.

Exploring the future of my Avatars Shape – part 4

sample1Turning Heads

Our avatars don’t look real. Not at any point can you say an avatar in SL looks real. Even with the advances in features such as mesh and material mapping we can’t make an avatar look photo real yet.

But looking real is not the only thing needed to trick you into immersive situations, if it was then you would not become so involved in the characters of the most colourful animated movies.

sample3Over the years i’ve adjusted and improved my avatar. Maybe i thought i was making him look more real, but i’ve probably just been upscaling the character detail so he shines with more clarity the personality i want him to express.

I’m now turning my attention to the head of my mesh avatar and this is where things get crazy. I could go for a photorealistic head, but would that just lead to uncanny valley of walking dead? I could just replicate the SL avatars head which is only normal compared to other default avatar heads. What if i go the pixar route and create something very stylised to amplify expression?

sample2I created a mesh version of my avatars current head to see just how much life is lost in the translation. The SL avatar uses a type of animation called ‘BlendShapes’ which you assign a ‘shape key’ to in your 3D modelling program for smiles, laughter and other expressions. There is no way at all for creators to tap this feature of the SL avatar so to replace the head we loose the connection with these facial expressions.

We also loose the ability to blink since the eyes use the Head texture of the default avatar for blinking. Some people have figured out some tricks for mild casual expressions and i will probably do something similar with my own but needs more experimenting.

meshheadBut expressionless avatars might not last forever. The heads I’m experimenting with now are being blendshaped even though i can’t use them on SL avatars. Software such as faceshift and Mixamo already offer face mapping to avatar, while 3D sensor cameras are pushing into the mainstream.

So what should i do, stick with the old avatar look, or break free from the mold and go somewhere no ones gone yet with an SL kid avatar?

Stay tuned to see how this all unfolds :-p


Getting Wet Behind The Ears

July 10, 2014 in Making a mesh by lokieliot

So amongst the excitement of Experience Tools and Skill Games announcements, something else happened this week. LSL Materials Parameters.

These are basically new commands for scripters to control the normal and specular mapping of an object. This is great for creators as material mapping, especially specular mapping has allowed for some very cool effects

You can make objects look more metallic and other objects wet or damp. In New Babbage i used specular mapping to make cobbled sidewalks look wet and have puddles. Windows reflect light like proper glass.

What adding LSL scripting control to materials allows is the ability to script the normal & specular map for certain changeable scenarios.

My first experiment with the new LSL Parameters was to create clothing that appears to get wet when you enter water. Some people had tried this before by simply changing the texture but now we can change the actual specular shine of the object for a proper wet look.

I didn’t stop at just clothes though. Since I’ve been working on a replacement MESH avatar body, i had a go at making the whole body look wet.


Stage one: DRY… Stage 2: WET!… Stage 3: Drying out…


The results were very promising. When you enter water the clothes and body become wet and when you leave the water the clothes and body gradually become dry again. The script itself is as low on server checking as possible, the last thing i wanted was to add scripts that cause lag. I’ve yet to consider wether to make all my future clothing ‘wet’ enabled or just the summer range.

Of course you need to have advanced Lighting Model enabled in your viewer before you can see all these kool extra effects, and a year after Materials first appeared many still are unaware of this feature. Some simply don’t have it switched on due to having old computer equipment while others turn it off because shadows grind everything to a halt unaware you can switch shadows off. I have a pretty up to date mac hardware and shadows kill my experience. Shadows should have it’s own separated tab so it does not scare people away from switching on advanced lighting.

Exploring the future of my Avatars Shape – part 3

July 4, 2014 in Making a mesh by lokieliot

fittedclothesSince i reached a point where I’m happy with the mesh shape of my avatar and how it moves, i’ve not been able to take it off.

I took my new body for a spin at SL11B with new shorts and vest specially created for the body shape. This allowed me to create clothing that fitted perfectly with the body and didn’t even need an alpha layer to hide the body under it, even as the vest hugged the body tightly. But this has nothing to do with the ‘fitted mesh feature’ which i did extensive experiments with.


Fitted Nonsense.

I’ve spent the better half of two months now experimenting and researching the fitted mesh feature. With help from Avastars Gaia and others who have dabbled in it i have come to the decision that i won’t be adding the feature to my new Mesh body… well, not in its full form.

How i’ve come to understand it, fitted mesh fits as long as you stick to the default SL avatar shape and i really do mean DEFAULT. As a small child avatar the arrival of Mesh meant i could smooth over the bumps and hiccups caused when deforming (squishing) the avatar to be child size. Fitted Mesh simply brings back the bumps and hiccups because its following the rules of the default avatar.

So if fitted clothing shrinks horribly on a child avatar, then perhaps i should start my clothe creation on an avatar shape that is already deformed (squished). Using the awesome Avastar blender plugin i was able to import an XML file exported from SL that contained all the deformation presets for a typical child avatar. My first results were very promising but the drawback is that creating a shirt that looked great on a small avatar meant it was no longer following the Fitted rules of the default avatar. This means squished bits like the pokey shoulder blades of doom still have to be masked. Another issue i found was that once you stray from the default avatars shape, the deformation sliders start to loose there strength. My friend Marianne raised this issue during my testing, showing that the Shirt would not stretch enough to cover her tummy.


Some friends try my test fitted shirts. Marianne demonstrating how the waist of the shirt fails to deform at the same strength as her actual avatar even though they are weighted exactly the same.

This weakening deformation issue is the main reason my Mesh Body will not be 100% fitted mesh. I managed to make the body so you can enlarge the belly and feet, but when it came to allowing for more muscularity in the arms and legs the sliders had lost proximity 75% of their strength leading to little or no change in the body shape and making all the hard work pointless. I don’t fully understand why this is, but from what i could gleam from Gaia and others, any fitted mesh will reference the default adult avatar shape when deforming regardless of how you have rigged and weighted your avatar.

Fitted Mesh is a great if somewhat complicated feature and for those making clothes for adult avatars it’s very handy. That being said , it will give a little bit of extra customisation for my future clothing, but i won’t be promoting it as fitted, because thats not what it’s doing.


Bug Hunt

There is a bug i need to present to the Lab once i figure out the best way. You’ve all probably seen it at some point and seems to effect some people more than others. I think i’ll call it ‘the Joint Rig Bug’. Basically you wear a ‘joint rigged’  item rather than a simple rigged item. Joint Rigs change the overall shape of the skeleton your avatar animates to. It can be used to make petits, animals or creatures with long arms and short legs. In my V3 shirts i use it to raise the shoulder joints to get what i consider better pivoting of the shoulders in relation to the neck.

The bug happens when you take off the joint rigged item or replace with a different one. What should happen is the skeleton should return to the default joint rigging of the avatar but quite often it will get confused and make your limbs go bonkers resulting in large heads, long arms, eyes popping out, and stretched bodies. Sometimes your avatar will appear in front of people failing to to rez the joint rig without which you look stupid and you don’t even know its happening because on your screen you look fine. Only way to fix the issue is an old faithful relog.

Now my mesh avatar is a joint rigged avatar and already people say i don’t load correctly, so i need to see if the Lab is aware of it and have a fix down the road somewhere.


Long necked Loki, or ‘E.T. Syndrome’ – This bug is annoying


People want my body.

I got great comments about the shape and detail of my mesh body, as well as a lot of interest in when i plan to release it for people to buy for themselves. Well that will all depend on my next line of experiments.

There are a number of things i need to add to a commercial version of the mesh body. First i need to test to make sure it works well with a number of sizes, but i also have to make sure its easy to customise, wether by tinting or changing skins. Customising your avatar is a fact of virtual life so i need to really think hard about it.

I am considering possibly two versions, one where you can use the default avatars head with its expressions, but also one with a mesh head.

There is also the issue that users will not be able to use any other clothes than the ones i make for it. It’s a completely original model and in no way based on the default avatar mesh. So users won’t be able to use old clothes with it, nor can they use anyone else’s clothes with it. This leaves accessorising the mesh avatar solely  at my store which is great for me, but not for the community. So i can see a need to offer other creators the opportunity to make clothes for my mesh avatar, perhaps by suppling a mesh model to work from.

Currently Linden Lab are working on series of LSL commands that will allowed script monkees to control material mapping. I’ve been preparing for this by experimenting with the idea of having the mesh body changing from looking dry to looking wet by changing the material mapping. First tests seemed promising, am now waiting for he LSL additions to be released. This may lead also to clothes that change their appearance in water.


Bonus of mesh bodies is you can use the new materials feature to add some nice lighting effects to skin.


There is so many little extras i could build into the mesh body, such as cartoon cell shaded modes, footprint sounds, different types of hand poses. But I’m also conscious about Avatar Draw and Script weights.

These are fun times :)
