Fitted Mesh

Second Life & Virtual Reality

by

We are getting closer to hands on. The Oculus Rift is to release in the first quarter of 2016. At this point I think the first round of pre-release technical challenges has been met. So, any possible delay would be from manufacturing and supply problems.

Now that the Samsung Galaxy S6 is in production the supply of display screens for the Oculus should be adequate.

Unity and Unreal, game engine platforms, are both announcing support of HTC RE Vive. This means game developers can move away from having to develop support for the various VR headsets and use the support provided by Unity and Unreal. This saves developer’s time and means new games will move through the development pipeline faster.

Second Life: Mesh Bodies

by

Coventina Dalgleish posted in the SL Forum: General Observations On Mesh Bodys – 4/6/15. Coventina came across a mesh body that has 2 million faces. OMG!

The question asked is, don’t the Lindens have a limit on the size of mesh uploads? Well, yeah. They do. But a body is often 3 items, the hands 1 or 2 more items, the feet also 1 or 2 items, and the head another item. So, while it isn’t easy it is possible to get to 2 million faces without exceeding the Linden upload limits per mesh part, just make lots of parts with lots of materials.

by

From Slink’s official announcement (quoting and paraphrasing):

Thu, Aug 28 2014 11:39:30 AM PDT

Physique 1.4 is now available at the Slink Mainstore. If you own this body, please visit the redelivery terminal to get the new version sent to you. If your purchase is not on the list, please contact Slink Resident for a redelivery!

The new body has a few very nice new features, and resolves some of the issues experienced by users of the previous version.

Fixes:

  • Resolved a small geometry issue that was causing “ants” (small gap) around the neck seam between the body and either the visage patch or the SL default head, on lower Antialialising settings.
  • Resolved an issue with the weights on several vertices on the underwear layer that was causing it to clip through the clothing layer on the pelvis region.
  • Resolved an issue that was causing the Visage neck patch to throw an error when the Neck Fitting buttons were pressed on the Alpha and Clothing Layers HUD.

New ‘Starter Avatars’…

by
New Avatar - Interesting Mesh Density
New Avatar – Interesting Mesh Density

OK everyone is posting about these.  If you haven’t already heard, you have to be hiding. They are far better than the Ruth and Roth avatars from earlier times.

They are interesting and noobies will look much better. However, noobies will still act like noobies . They won’t be all that hard to recognize.

However, Saturday when I was trying to play with the new avatars the SL system was acting up. The Choose an Avatar panel did not want to load. I kept getting an empty panel. I left the panel open and relogged, that got it working, or it may be just the relog did it. Or my region may have been having difficulties.

Once the panel was loaded then some avatars would not load. I would get what looked like an LOD4 version 0f the avatar only, very bizarre looking up close but ok from a distance. Switch to another one and later retry the one with loading problems, seemed to work.

When you wear one of these avatars a folder is created in the Clothing folder of your inventory. The ‘Lucy’ avatar is of course in the Lucy folder.

These avatars completely replace, well are worn over, your system avatar and a full body alpha mask hides the system avatar. They are complete mesh bodies and clothes. I am not sure why they made them No-Mod.

Second Life Fitted Mesh Doesn’t Fit

by

Well… surprise, surprise…

There is an excellent thread in the Second Life™ Forum about the designer side problems of getting fitted mesh to fit. See: Blender/Avastar [Fitted Mesh]: Need help/advise with a few issues. Posted by Zakiel Windlow the problems are clearly expressed. Zakiel includes a great set of images to show the problems.

Zakiel explained where he is coming from and what he has realized, “A few weeks ago I was using a workflow that gave me good, fast and (more or less) SAFE results:

Standard rigging and 5 or 6 sizes (or more). But I wasn’t happy, anyways. I always wanted the “fitted” mesh so all the girls could use my clothes without problems or restrictions. That was what I thought or was expecting.

Now I realize that with the fitted mesh there are restrictions too; and the workflow (for now) is harder, longer and not safe as the standard rigging. I have to check the fitting with big breasts, small breasts, big+high, big+low, small+high, small+low, big+close, big+open, big+high+close… You get the idea… And what works for 1 combination probably won’t for the other…”

The State of Avastar & Fitted Mesh

by

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:

‎2014-04-14 06:35 AM – edited ‎2014-04-14 06:36 AM

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.

(Reference)

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.
