Avastar adventures

First of all, I must say Eleanora  Newell is great, as she is so fast at answering and helping with Avastar.
This is what she said on  http://blog.machinimatrix.org/workflows/classic-fitted-tips/ , where you find useful tips, tutorials and a blog about how to use Avastar.

Hi, Delia,
I need a picture showing me your shoes in object mode and on the right, I need to see the property shelf (toggles letter P) showing me the scale and rotations transforms for the shoes, please. Remember that I told you that if the shoes had incorrect scale (especially in the negative), it would cause reversed normals. In addition, if the scale is incorrect, you must then check the normals again after you correct it and make sure the normals don’t need to be corrected, because often they do. And again, this is NOT something Avastar does, this is all about the models and how you model, which includes if you keep correct scale and check for inversions throughout the modeling process.

Actually I had forgotten scaling is important, as this solved another issue I had had and Eleanora had told that to me already. In that case the problem was fixed, but this seems to be a more tricky one.
Here is what I did:
1 .
scaled, as you can see on the right.  CTRL+A

flipped normals and exported as in the  picture I  posted yesterday , dae - Avastar

Reimported them in Blender to see if everything was ok. Nope, flipped normals.

Checked if it is my problem or Avastar problem, exporting the same file using Blender- dae
Reimported the dae file.
Perfect.

So, as I am sure Avastar works and was tested, and I know I am soneone who can find bugs anywhere, I can think of the following reasons:
a- the program is so perfect that it fixes things which are not ok, so it interprets the lack of inner faces as something not ok and flips normals. Blender export does not do that, so it must be some extra line in exporting and checking.
b- there is some problem with vertex groups ( I added some for color  stripes etc) , or in interpreting the weights taken from Slink feet . ( I set the file as expained in the tutorial ). I exported as avastar .dae Slink feet for a check, and the file has no ending, I have to add .dae manually to be able to read it. ( see the picture in my previous posts)
c. There is some problem with texture, as I noticed before ( in Blender export for sl, not Avastar ) that it could give some problems when exporting it, so Texture might be an issue. No clue.

Struggling with Avastar 1.2

Trying again. I prepared again the Slink feet as explained in here http://blog.machinimatrix.org/workflows/classic-fitted-tips/ , appended my shoes again, removed skeleton and weights , applied them again, here is the result
Found what was wrong: never apply weights from Slink if your shoes still have a mirror modifier not applied, this will be the result. Weights from mirror to mirror cannot be changed, at least not in this case.
and of course checked normals again
So I finally found a solution.
Export Avastar dae.
Find the file with no ending .
add .dae manually
reimport it to Blender, you will see normals flipped
Flip normals
Export it to .dae using blender export

Struggling with Avastar

Hi everyone,

I have been struggling for a month or so now, trying to create some shoes. Apparently I can save and upload them properly using Blender save, but not Avastar, as it flips normals. Any clues?
See the pictures below.
 Here is my file, proper normals
 My file loaded as Blender file, after saving ( but no weights), in red, and in white, as Avastar weighted
 This is how it appears when saved with Avastar dae, and sometimes the file is not even saved,
this is how I save.
I guess there is something in my file which makes the program crazy, no idea what it is .

Avastar - May 2014



Avastar is giving me some problems, as the corset I am creating works there but not in sl.  I used fitted mesh, set belly to 0 but the avi is still too large.
 I created the corset on the stardard avi from Avastar.
Any help?

▀▀▀▀▀▀▀▀▀▀▀▀ ▀ ▀ ▀ ▀ ▀ ▀ ▀ ▀ ▀ ▀▀▀▀▀▀▀▀▀▀▀▀
Installation of Avastar test version 1-1-1039.
We have found that you will need to:
1. Install the zip addon.
2. In the addon tab, type Avastar into the search field.
3. Verify that Avastar is enabled.
4. Save user settings.
5. Restart Blender.
6. If you are in Blender 2.7x, the Add menu is now at
the bottom of the 3D View window.  The shortcut is
Shift-A.

If it is stubborn, uninstall Avastar and restart Blender
before proceeding with the steps..

Still stubborn, Set to Factory setting, uninstall Avastar
and proceed with the steps.

● Workflow for  previously weighted mesh:

1.  Have your mesh and the avastar figure and rig ready (I like the meshes and rig on different layers for ease of selection, you can use shift select to add more than one layer, but you can put them as you like).

✱ NOTE:  It is important to model over the default shape.  Once the model is complete and parented to the rig, with sliders attached, you can load the shape you wanted to use.  If you did the five standard sizes, hopefully you also included default.  If not, take the one closest to default size and edit it to the default shape. ✱

2.  Select your mesh and the rig.  In the Skinning and Rigging panel, set Weight to "Keep".  Shape sliders should be on by default.

3.  Press the Assign Armature button.  This changes the options for the next step.  At this point both your mesh and rig are still selected and can stay selected for the next steps. 

4.  For Fitted Mesh, press the plus sign by "Deform (Fitted)..." to open the panel where the Fitted button should be the one enabled.

5.  The deform panel has been updated to try and make it as simple as possible.  Since we are doing a garment that was previously weighted, change Weight to Move.  This will move the weights that were originally mBones (SL) weights and moves them to the corresponding cBones (volume/collision).  If you want your mesh to also have weights place on the cBones for which there are not corresponding mBones, checkmark the Generate Weights button.  Apply configuration.

6.  The mesh is now ready for you to test with sliders.  Go to the object properties to test the sliders.

7.  Go to Show bones in the Avastar tab and enable weight.  This will make the sl base (blue) and volume bones (orange octahedrons) visible and put you in the weight room.

8.  Enabling Stick will make the SL base bones easier to work with.

9.  Use the SL bones to pose, and the volume cbones to weight.

10.  To update the weights while you're painting, press alt-q to see changes to the mesh after you paint weight.

▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀

● For unweighted mesh:

1.  Have your mesh and the avastar figure and rig ready (I like the meshes and rig on different layers for ease of selection, you can use shift select to add more than one layer, but you can put them as you like).

✱ NOTE:  It is important to model over the default shape.  Once the model is complete and parented to the rig, with sliders attached, you can load the shape you wanted to use.  If you did the five standard sizes, hopefully you also included default.  If not, take the one closest to default size and edit it to the default shape. ✱
 
2.  Select your mesh and the rig.  In the Skinning and Rigging panel, set Weight to Meshes, Bones or Empty, depending on what you want weight from.  Remember that to use Meshes means you must have the avastar, or another mesh with weights, visible for the copying to occur.  Shape sliders should be on by default.

3.  Press the Assign Armature button.  This changes the options for the next step. At this point both your mesh and rig are still selected and can stay selected for the next steps.  

4.  For Fitted Mesh, press the plus sign by "Deform (Fitted)..." to open the panel where the Fitted button should be the one enabled.

5.  The deform panel has been updated to try and make it as simple as possible.  Since we are doing a garment that was previously weighted, change Weight to Move.  This will move the weights that were originally mBones (SL) weights and moves them to the corresponding cBones (volume/collision).  If you want your mesh to also have weights place on the cBones for which there are not corresponding mBones, checkmark the Generate Weights button.  Apply configuration.

4.  We're doing Fitted Mesh, so press the plus sign by "Deform (Fitted)..." to open the panel where the Fitted button should be the one enabled.

5.  The deform panel has been updated to try and make it as simple as possible.  First we want to change Weight to Swap.  This will swap the weights from the mBones (SL) weights to the corresponding cBones (volume/collision).  If you want your mesh to also have weights place on the cBones for which there are not corresponding mBones, checkmark the Generate Weights button. 

Now, here's the important part:  If you want to have the mBone groups to weight to, you will ALSO checkmark "Keep groups".   The mBone groups will be empty.  You will have them though if you want to weight to any of them.  You can delete any (in the vertex groups list) you don't use.

Apply configuration.

6.  The mesh is now ready for you to test with sliders.  Go to the object properties to test the sliders.

7.  Go to Show bones in the Avastar tab and enable weight.  This will make the sl base (blue) and volume bones (orange octahedrons) visible and put you in the weight room.

Avastar 1038

Trying to add some cloth and collision. The lower part of the default avastar  avi cannot be selected in object mode, not does the upper part. If you select it from the panel on the right, you can obtain an edit and select, not select obj mode.
Selecting an  appended workbench works
Selecting lower body mesh works as well, as I can move it, but it is not highlighted

Friday, March 28, 2014

-See , right and left pectoral are not visible in the second picture, yet I can select them in the panel on the right.
Trying to solve the problem with buoyancy and fitted mesh
Avastar 10.1038
New bug

 and something more, see this pose, it is smooth in avastar but..

Something went wrong when uploading

more on the waist

Avastar workflow for version 1038

this is the workflow posted with the permission of Eleanora Newell, for Avastar test  10.38.
Even if Blender says it is properly installed, if you see something wrong I suggest that you uninstall and install it again from scratch.  New versions are coming out, so this will probably work just for this version

strange weights in avastar

this is weird, the two verts come out either I weight them or not. As you can see, there is O weight and I do not understand what is happening. They were red before, same result.

Avastar 1.1.1038 fitted mesh

Here we are with the latest test version of Avastar.
Fitted mesh does not work at all for me.
Eleanora Newell kindly sent a note with workflow, here is what  should happen:

"4. For Fitted Mesh, press the plus sign by "Deform (Fitted)..." to open the panel where the Fitted button should be the one enabled.

5. If you have done weights from meshes or bones, change Weight to Move. This will move the weights that were originally mBones (SL) weights and moves them to the corresponding cBones (volume/collision). Apply configuration."

Weight to move does not show up, nor does the menu with bones. Frustrating.


Ok , now I know what a "stubborn install" in Blender is. To solve this problem you need to reinstall Avastar from scratch.

Anyway one previous Avastar ( can't remember which one, 24 perhaps? ) worked with fitted mesh, as you can see here below)
 I was still wearing something below not to appear naked to someone without an updated viewer.

fitted mesh in SL

So after working for some days I came to some conclusions: I have not found a solution to weighting proper both for enlarged breasts and  buoyancy, as they need a different system of weights to go from small to big ones or from "low" and "up" breasts.
Avastar works properly , even if it gives me messages of error.
If you haven't a mirror mesh it is not possible to use X mirror in weights , meaning the dress of the picture below is not properly mirrored because of the scarf on the neck , as I removed the faces below.
Here you can see the model in the beta grid ( different r and l shoe, yes, I did not mind changing them). It works properly.  It is more or less what you see in Avastar , but not exactly.
Below same sl official browser, normal grid
 The shape was slightly different, but the dress behaved anyway in a different way, not following the breast enlargment as it did before. True I also fiddled with mchest and other bones as fitted bones seemed not to be precise for the back of the dress, no way to paint a proper alpha.Same on the hips, they look ok in Avastar, do not in sl as the avi comes out. Or maybe I was so busy I forgot to press alt Q ( remember, the important keyboard shortcut to update when you are weighting). Will keep you posted about that. Blender crashed when I tried to save and close the program.
Then I tried in Phoenix, as I wanted to take a proper picture, but I have not updated to the latest, and I am not sure it can see fitted mesh, so this is the result
Which means that if you buy a fitted mesh dress you run the risk to be seen  this way by those who do not have the latest  or official browser.   The latest Phoenix with fitted mesh is out
http://wiki.phoenixviewer.com/firestorm_release_4.6.1.40478_change_log
but I have not installed it yet.
Imagine going to dance or to a concert where people can still have old browsers.
There is also a strange glitch in the dress I made, which is properly uploaded as a usual mesh, but if I texture it with a png  look what happens if I rezz it :
The mesh is the same, png in blue textured, worn, and looks normal, same texture colored in pink, and no texture on the left. If you use a jpg no problems , it looks ok even rezzed.
Any feedback is welcome
So here is what happens in Avastar
As you can see , the problem is about the same, so I tried all possible bones as below

butt is not enough

so I tried with mpelvis, same result
pelvis
upper leg did something, did not dare to see what happens if you sit down
lower back seems to be what disturbed. It can be noticed there is a line on the waist, like in sl avi, not sure why

working with Avastar for fitted mesh

Actually Eleanora Newell is helping a lot. This picture as I need to understand where weight bones is and what you need to highlight to get fit or classic mesh appear
second part of menus, no bone weight

Whatever it is, I could save the dae file and load it in the beta grid, it works. Thanks for Avastar the the work put in it!
Exported and reimported the dae file in Blender
