I finally finished this SL mesh clothing video series for Blender 2.49. When I started planning it, you couldn't export a rigged mesh from Blender 2.5x that would work in SL. However, now you can. :) So, I'll update the series soon for Blender 2.5x users.

Exporting a rigged mesh from Blender 2.58 does not work in SL at the moment.

See: CTS-718

There is a problem with Collada 1.4.1

To quote Prep Linden:

The core issue with this particular defect is that we do not fully 
support collada 1.4.1 at this moment.
I have implemented partial support for 1.4.1 but there are still
a couple of loose ends that need addressing - so till then your
rig will come in collapsed (july 28 screenshot).I still intend to revamp the rig import code - along with your
suggestions there are a number of other areas that need to
be refactored.Till the code updates are in - I suggest you export your rig with a
version of blender that has the collada 1.4.0 exporter (I used 2.49).

These are fantastic tutorials Asha, and just what people needed! I learned a lot from it and hopefully rigging will be a little less painful. Thank you!

@all: I'm glad you guys have found it helpful :) Thanks for watching.

@Ron: You can export a rigged mesh from Blender 2.58.1. I have been exporting and uploading rigged mesh from it for awhile. That version has a patched collada exporter that also lets you "export only selected", which is a godsend. You do have to download this version from graphicall.org though.

Ashasekayi!  Your videos are like M&M's...I couldn't stop watching them.  They are excellent and I learned a mooseload of new stuffs.  I can't thank you enough!!! 

I have one comment/question.  I have found by random flailing around with Blender :matte-motes-nerdy: that if you just delete all the shapes except for the "basis" shape for each body part, it  deactivates the corresponding vertex groups and it is then not necessary to remove them.  If you go to the shapes subpalette and click on the left facing arrow, then click the x "delete" button repeatedly, you can quickly just remove all the shapes.  And of course if you get carried away, as I always do, and delete the last one (the basis), I just hit ctl z to bring it back.

I'm not an advanced Blender user by any means, so I might be off base with this.  Please let me know if I am.

Hi Nacy :)

The method that you described would work if you are using the avatar.blend file since that file includes shape keys. However, if you use the Wiz Daxter plugin, the avatar doesn't import with shape keys at this time. So, I explained how to get rid of the morphs in a way that works independent of whether you use the plugin or the avatar.blend file.

Excellent!  Thanks so much for clarifying.  Too bad the Win Daxter version isn't that easy! lol.

And now I'm going back to rewatch your vids.  They're so great.

Glad you liked them Nacy ^^

Thanks for bringing up the shape keys though. Some might prefer going that route.

Thank you Vivienne! :D in blender you can move the joint points of your armature and then apply the visual transformations, so you can have a tiny o giant avie without problems! (or a small avie with giant arms if you want, lol)

And, please lindens, stick this topic on the top, lots of question on the forum are about rigging in blender ;)

I guess can be handy for all of us.

Ok..I was challenged by the tediousness of deleting each vertex group one by one.  I just knew there had to be an easier way xD!

Anyone interested can go here:

blenderartists.org/forum/showthread.php?158240-Batch-Delete-Vertex-Groups-script

Copy this script to your basic text editor and change the extension to .py...I named it:  Delete_Vertex_Groups.py

Then drop that file into your blender scripts folder and when you are in edit mode it will be with your scripts.  Click it and you'll get a handy pop up menu of all your vertex groups so you can batch delete the ones you want to remove.

Works like a charm in blender 2.49b...I haven't checked it out in 2.58 yet.

 

Edited to add: The script doesn't work in Blender 2.58, but now that I look at the way the layout works it's much simpler in 2.5 to run thru the vertex groups and just press the minus sign to delete the ones you want.  Somewhat similar to deleting shapes in 2.49.   Unfortunately CTLZ doesn't undo here so its easy to delete too quickly and have to start again.

Cheers for that script Nacy ^^ It is a tedious process. But, you only have to do it once at least.

 

@Danial: Sorry, I don't use Maya. However, there is some general purpose information in the primers. Plus, Wix Daxter sells his plugin for Maya as well.

Wonderful tutorials, thank you so much :)

But I have a question: In video 4 ("Skin the Clothing Item"), suddenly at 0:53 in layer 6 to 10,  there appear LOD variations of a shirt... it would be very interesting, how to make those.

Thanks for your beautiful tutorials, finally I understand a lot of things: are the most clear and useful tutorials I've ever found.

Please show us how you do your perfect other LOD :)

Yaaay!

(I frankly don't see how you and Gaia find the time. It takes me 8 hours to wake up which leaves the remain 4 to get ready for sleep - and that's not because I'm bored, far from it!)

nice to hear :))

I think, I found a way to do that LOD stuff? Is using modifier "Decimate" a good idea?.

was thinking the same..

or, as ( I am a noob modeler) I start with very low poly then use multires (and all the loopcut I need) to define the stuff.....saving copies of low-medium-high multires could work?

I personally don't recommend the decimate modifier. It really only does a slightly better job than the automatic decimation that the SL uploader does. I'd suggest making LODs by hand if you want quality.

 

@Nirmanakaya: It would be hard to describe the process of optimization properly here. It is complex and depends on the specific model you are optimizing. For instance, the modeling process for something mechanical opposed to organic can differ in a number of ways. That being said, Jason Walsh has a good general video on reducing polys in a mesh:
