Challenge to setup rigged mesh

Still I need to understand something…

But I learned the following points from importing work…

• Before importing pmx, get rid of all joints and rigid bodies. You don’t need them and to be simple work in blender.
• Before importing pmx, you had better change Japanese material’s name to English. You could edit in blender but sometime uploading failed to secondlife (parse error).
• mmd_tools helps us for importing and editing pmx. We should add this on blender. https://github.com/sugiany/blender_mmd_tools
• Avastar helps not only secondlife born(armature) parenting but also exporting collada. If you would like to separate object and make seamless among them,  need “Weld Edge Normals” option in Avastar exporter. About weld edge normals, please see this post.  http://meshdolls.blogspot.jp/2013/04/avastar-weld-edge-normals.html
• One object should have 8 materials or less. You need to separate pmx mesh by “materials” with using mmd_tools “Separate by materials” in tool shelf. “Separate by materials” keeps armature modifier, materials, vertex group and shapekey information. No collapse meshes by shapekey (morph) incorrect data by this approach.
• In editing, you should always pay attention on shapekey. Basis! Basis! Basis!
• When you want to separate mesh more, don’t delete vertices. Create new material, assign vertices, copy material data from original to new one and “Separate by materials” in mmd_tools. If you just want to delete, you don’t need to copy material data to new one.
• When you want to copy mesh, Avastar custom mesh tool “Freeze Mesh” helps you. Getting rid of shapkeys but keeping morphed mesh, armature modifier, material (same name of original) and vertex group. To make facial expressions mesh, this freeze mesh is useful.
• When joining meshes to one, you should consider its materials naming. If you would like them to be different “side” in secondlife, you should differentiate material’s name. Don’t change its name directly. Make new material, assign all vertices and copy material’s data from original to new one.
• “Apply scale and rotation” – Avastar exporter does it by option but when pmx model scale and size changed for avastar or skelton base, apply them.
• Make T-Pose (rest pose) by using pmx born(armature) pose mode. You need to add armature modifier more and apply original one. Please see this page for how-to.  http://nixart.wordpress.com/2013/03/28/modifying-the-rest-pose-in-blender/
• PMX model has many “doubles” vertices. Mesh tools [Remove] [Remove Doubles] helps you reducing vertex count and getting rid of line on surface in the same material.
• PMX model doesn’t have lining faces backing for clothes therefore you should duplicate faces and invert normals of them. Please see this post. http://meshdolls.blogspot.jp/2013/01/making-liner-normals-inside.html
• Secondlife doesn’t support custom shapekey (morphing). We can’t export facial expressions by shapekeys to secondlife. So prepare facial expression meshes (materials) and control transparency by LSL(Linden Script Language). Please see this post. http://meshdolls.blogspot.jp/2013/04/avastar-weld-edge-normals.html
• Modify secondlife  born skeleton or avastar armature. Move armatures to same position of PMX armature. head, neck, collars, shoulders, elbows, wrists, chest, torso, pelvis, hips, knees and ankles are key armature points. Avastar armature is so special therefore see this video. https://www.youtube.com/watch?v=mL4X1AlMtVU
• Don’t use Avastar parent tool [Rigging] [with Weight Copy] nor blender parent [With automatic weight]. PMX model already has weight data. For parenting to armature, you had better use blender parenting(Ctrl+P) and [With empty groups].
• Modifier “Vertex Weight Mix” can add PMX vertex group weight to secondlife armature vertex group. Especially for body parts, you can get so excellent weight from original model mesh/vertex groups.
• In uploading collada file to secondlife, use [with joint position] option for body, especially including elbows and knees. Because secondlife armature’s joint positions are changed by modified for PMX born style.
• Some parts should not be used the above [with joint position] option in uploading collada. For example, changing side’s alpha scripted objects like “face and eye”. I don’t know why but we see flick model in-world.
• About image (picture) file, you would need to convert files to JPEG. TGA and PNG has alpha channel and secondlife sometimes can’t handle them correctly.

In addition, it takes over 2 years to understand/learn the above by try and errors. Still I feel I don’t know blender and 3DCG thoroughly. I really appreciate that Avastar Gaia Clary youtube channel always gives me many hints https://www.youtube.com/user/gaiaclary and so many blender tutorial videos and blog posts also help me.

Thanks, Enjoy and good luck

Mesh dolls posing

In wolrd, from my friend, I was asked how do you make dolls posed?
Aha, it’s not easy to set pose by blender.

OK, I ‘ll opne my work for mesh dolls.

I recommend you to use PMX Editor transform view and VMD play.

1) Open pmd/pmx models in PMX Editor.

2) Open “Transform View” in PMX Editor.

3) Load vmd file you like, from [モード] ([mode]) – [VMDリスト] ([vmd list]) – [ファイル] ([File) – [VMD リスト追加] ([Add to VMD List]) – sample is “イージーデンス”

4) Close the abvoe windows and play motion by check [M] and play [▶] botton. If motion is no played, double click motion name in VMD list window. You can see a model is dancing in Transform windows.

5) If you would like to save the posing, you should STOP playing motion!

6) Go to “Transform View” [File] and click [現在の変形状態でモデル形状を更新-頂点モーフ正規化]。

7) Click OK [Vertex Morfing re-calcurated …] (頂点モーフ再計算閾値) maybe 0.00001

8) PMX view would be updated to same posing in transform view.

9) Save the file as another name.

10) Open the file in Blender by pmd/pmx import tool.

11) If you don’t like physical setting, adjust it in PMX editor.

That’s all

Enjoy!

Of course and I’m afraid that it’s not for sale.

mesh head and facial emotions–not morphing

In secondlife, we don’t have morphing (shapekey) therefore use multiple layers (materials in Blender and faces in Secondlife) and change alpha with llSetAlpha.
HUD and llGetAngentInfo can control layers by Linden scripts.

Still it’s a primitive HUD but you can understand how we can control facial expressions by multiple layers.

Enjoy.

makehuman has seconlife export option

makehuman is designed to make human polygon as free software. It can export mesh object for several formats, includes collada.
If you select collada export, also you can select "Use second_life rig" option.
To export colllada for second life, check the following options.
- Rotate 90X
- Rotate 90Y
- meter
- Use second_life rig

Already rigged and weighted! You don't need adjust by blender, you can upload it as shape model into secondlife directly.

Also this is collada therefore import it into Blender and using PMX exporter, you can make PMX model. (don't forget changing axis-world and PMX bone should be used and weighted.)
