The State of Avastar & Fitted Mesh

Numerous people are running into the problem with their mesh clothes creations not working well with the Second Life avatar. Gaia Clary’s latest comment in the SL Forum is here:

Maybe I [Gaia] can add 2 remarks here:

  1. You could use the Morph targets to create a dummy character and implement the SL Shape sliders to shape the dummy into the SL shape. Then you can use that dummy as reference for making your mesh garments of course. But note that the morphs themself [sic] take no active role in the fitted mesh deforming.
  2. If you wanted to create something reasonable then you would create some sort of controllers that modify the Collision Volume bones. If properly done, then you could immediately see how your mesh would react in SL with changing slider values.

The main problem is to understand which bones are affected in which way by which slider. Most of this is noted down in the avatar_lad.xml file. And yes, in Avastar we actually have ported the SL Shape slider system into Blender This works as intended for the dummy itself. But for the mesh garments there is still something wrong (so right now we do not have a complete solution )

BTW: Blender allows to export shape keys to Collada, so in theory you could take our workbench blend file, then export the character with shape keys, and then try to upload that to Maya. Maybe that works, maybe not, I have never tried it myself.

At the Content and Mesh Import User Group we got some new information on the problem and what it might take to fix it. Don’t get your hopes up. It looks like we are going to have to learn to work around the problem. But, At least we know what the problem is and can quit wasting time searching through viewer code.  Continue reading

Second Life and What Fits

A couple of days ago Jeremy Linden put a new page into the Second Life™ Knowledge Base: Buying clothing that fits your avatar. The same day a post appeared in the Second Life Blog: Help Customers Buy Clothing that Fits their Avatars. Both of these target the confusion surrounding mesh clothes and avatars.

Consider. We started out with what I call system clothes. These are the decals we place on the avatar that look like clothes. This is the shirt or pants we make when use the features in Appearance. We hang prims and sculpties on the avatar to embellish the ‘decal’ clothes. These clothes fit the avatar perfectly. Consider ‘perfectly’ to mean no skin poke through. Continue reading

Second Life Avatar Shape

Loki Eliot has an article up titled: Exploring the future of my Avatars Shape.

The article is a good account of the problems and decisions we must handle when making full avatars and clothes. It is worth the time to read.

We have many considerations related to where the Second Life Avatar is going and how we will work with it. The Lindens see things in terms different from those we see. The Lindens are dealing with programming issues and development costs. Since they seldom make clothes and seldom are involved in fashion the priorities are lopsided toward the technical. Lindens may not change appearance/clothes for years.

Of course the majority of SL users have no idea of the technical complications. But, they are into fashion and may change their appearance several times per week, if not per day. So, the majority of users have priorities lopsided toward the aesthetic side. Continue reading

JIRA STORM-1800

The two big JIRA items relating to the Second Life avatar are STORM-1716 and STORM-1800. 1716 was the Mesh Deformer. It is considered closed with the release of Fitted Mesh. 1800 is the item that deals with the avatar weighting and mesh layout, which many of us still consider a problem.

You can see the partial fix discussed in 1800 in the Singularity Viewer. It uses the adjusted weights recommended as an improvement to the existing avatar we see in the SL Viewer. I’ve added the weight to a couple of versions of the SL Viewer. It helps. But, the patch only affects what I see not others. You can add the fix to your viewer using the file found in the JIRA.  Continue reading

Penny Patton on Land Cost

I like to think I am well informed and think about issues related to the subjects that interest me, Second Life™ being one of them. However, Penny Patton often points out things I completely miss. She has a new article out on land cost and Land Impact costs on tier. It is well worth reading. See: The Cost of Second Life Land vs. The Perception of Value OR Land in SL is Cheap! I took a little liberty with the title.

Image by Penny Patton – Can you find her in both images?

Penny says her avatar is in both images. I found her in the top image. Click, it enlarges. But, have yet to find her in the bottom image.  Continue reading

The Problem: Fitted Mesh an Alpha Tutorial

I suspect anyone that has worn mesh clothes is very aware of skin-poke-through and ‘holes’ from the Alpha Layers making parts of the avatar invisible. I am particularly annoyed by both. But, is there anything we can do? That is the question asked at Fabulously Free in SL. Here I’ll provide the techy answer and information. I’ll also link to good tutorials.

Fab’s three advisors answer the question. Their answers are straight forward and provide the advice most of us know. But, there is a more complete techy answer. First I’ll summarize their answers then get into the tech. Continue reading

AvaStar 1.1 Video Released

Gaia Clary has a new video tutorial out. This one uses Blender 2.70, which has been released. Using it and the newest test version of AvaStar Gaia shows us how to initialize weighting for Fitted mesh.

The work flow for moving existing weighted items to collision weighting is covered in the first part of the video. Mid-way in Gaia covers starting weighting from scratch. The later part of the video is about using the shape sliders to test your weighting. Continue reading
