collada bone animation with Blender 2.49

[bartekd]

Hi,

Has anyone been able to export a Collada file containing bones/
animations from Blender 2.49? Is there some special settings that we
need to use? I tried a lot of different options but none seems to work
fine so far...

Thanks
Bartek

Blender 2.49 does not support bone export yes

Are you sure?

Bones export works for me in Blender 2.49b and Collada 1.4 Exporter.

I'm having the same problem, I have a post also a few pages down. I
exports bones, and when looking at the animation library in my model
as well as the mario_testrun model(from the demo), i didn't see a
difference in the way the data is declared. I was even able to
capture a bone from my model. The problem happened when i called
Container3d.update().

Good to know. Can you elaborate? What do you mean they work?

What I experienced is that there is indeed bone information encoded
into the COLLADA file but Away3D doesn't seem to be able to playback
animation based on those bones. Honestly, I didn't try to animate the
bones proceduraly, so maybe this works... but for the moment what I
need is something like the mario demo but exported from Blender 2.49
(and in case someone wonders: Blender 2.5 Alpha 2 doesn't even export
COLLADA properly). I also triend to import the mario COLLADA file
(which is exported frm Maya) into Blender and it failed - so there
must be something in this file that Blender does not understand.

I'm only using the exported Bones procedurally at the moment
(accessing and modifying them in code). I didn't try exporting/playing
animations, so I can't help you with this one. Sorry.

I'm currently working on a project where I get Collada files exported
from Maya and they contain armatures (no animations though). Importing
them in blender works just fine. From what I can tell, the alpha
release even does a better job at restoring the armature (in 2.49 you
would have to bind add the armature to the mesh again and restore
vertex groups, whereas in alpha it's all good after the import).

Maybe it's the animations that blender chokes on?

I took the time to sift through the files a bit, and i think i
pinpointed the problem. I looked at the mario_testrun.dae and a
blender exported collada file in a text editor. I see that the maya
exported mario_testrun.dae has a section titled <library_controllers>
that the blender exported collada files do not. <library_controllers>
follows <library_geometries>. My blender exported collada file
doesn't have that section. My experience with python is very limited,
as with blender scripting, but I don't think it would be a very
difficult endeavor to append <library_geometries> to the colloda
export script. I'll hopefully get around to looking at it, but
probably not today. I'de be feeling around in the dark a bit.
