Rigging working in Blender 2.5

[Tapple Gao]

I submitted a patch to blender and a bug report to secondlife that, together, should get meshes rigged in blender 2.5 working. If you are not afraid of patching the blender source code and compiling your own blender, you can upload rigged meshes direct from blender 2.5 using this fix + SL bug workaround patch: http://projects.blender.org/tracker/download.php/9/498/27598/16835/collada-bone-rot-issue-27598-1.patch

Thanks for the information. Would you happen to know if this patch is included with the GSoC Pepper Branch builds at graphicall?

[Tapple Gao]

I made the patch against trunk. I'm not a gsoc student, so didn't use that branch

[Ashasekayi Ra]

Ah I gotcha. What is the SL bug workaround patch that you mentioned in the original post?

[Tapple Gao]

this one fixes the bug in blender and works around an SL import bug: http://projects.blender.org/tracker/download.php/9/498/27598/16835/collada-bone-rot-issue-27598-1.patch

I see. I misunderstood your first post. After using the patch and re-compiling Blender, the dae file created won't load the rig into SL. It acts as if it has a partial rig. The original file has a complete rig however.

Hi,

Things I have found so far with this patch::

1. You only need Vertex deformations ....turn off Bone Envelopes in the Armature modifier

1. You must apply the modifier before Collada Export as the current exporter only exports the base object

2. Make sure that the object you are rigging is parented to the avatar Armature not the Object otherwise the rigging will not work.

3. You have to make a weight entry for all vertices even if its 0. Otherwise vertices/faces will not show up.  Weight your object to the mPelvis completely before you start weighting other joints to get all the vertices lined up for export.

There is likely is a better way to do this in blender 2.58 but this is only way I can get anything to export in a resonsble fashion.   Still having problems with complex objects being rigged and able to be uploaded to SL. The preview window works and shows the object in its correct position but fails silently to upload. After this happens trying to quit SL fails and it locks up.

Nothing new about any of your 4 issues chodai; that's how rigging works in blender 2.49 too

[Chodai Yoshikawa]

Ah perhaps they are.. I don't rig much ...still learning, but a lot of these things are defaults for 2.49b exporter/rigging so I have to learn when and why they need to be pressed in 2.58 rather than relying on default settings.  Other newbies like myself might like a checklist

Reporting back on my issue with the patch:

After re-installing the patch today and having the same issue with uploads, I fiddled about in a differing program to try and see what the issue was. It turns out that it would only upload if I changed the name of the armature to "avatar". Why... I have no idea. But, the model uploaded fine after I made the name change.
