Also, the other question I have is in regards to animation. Can I import my bone and keyframe animation into Blender? I had read somewhere on these forums that it may not be possible. It may not be trivial, but it ought to be possible. The armature api has changed significantly in the last couple r...

I've been struggling with this a bit, too, maybe you've seen this thread: http://www.blender.org/forum/viewtopic.php?t=8144 Looking at the code of existing exporters might give you some hints, atleast that's how I learned most of the details of Blender's matrices, and the documentation and, as kakap...

I got it. Just like the documentation says: localMatrix: The matrix combination of rot/quat/loc. This means that it is relative to the bone's restpose matrix. If you set a keyframe with identity matrices for all bones' localMatrices, you get the rest pose. Regarding the "how armatures work" illustra...

Thanks for the answers! But I still haven't had any progress. In the link an-toni posted with the explanation of the armature system, there is no mention of localMatrix.

What space is a posebone's localMatrix supposed to be in? I'm trying to import animation using the pose module and would need to know that.
Thanks!

I wrote an exporter to MD5 (Doom3 engine model format) that is based on Jiba's Cal3D exporter. It's updated and works with 2.40. Maybe you can get some ideas from there.

Yes the bounding box is available through the Object's getBoundBox method:

I learned alot by looking at Jiba's Blender2Cal3D exporter:

object.getAction():

BPY_API doc wrote:Returns an action if one is associated with this object (only useful for armature types).

Is there a way to get all the actions linked to an object, if there are more than one?

Is there a way to get the current position/rotation of a bone? I'm having trouble exporting animations with a script that uses the IPOs to calculate the bone positions. If I bake the constraint animation to IPOs, the script only sees empty IPOs. I don't care if it's a bug in the script or in Blender...

In the UI, when you parent a mesh to an armature with Ctrl-P, you're presented with a question wether you want to parent it to a Bone, the Armature or the Armature Object. For skeletal animation, you have to select "Armature". When I use armatureObject.makeParent() in python, it seems that that's th...

There's a .getRestMatrix() method for bones, but no .setRestMatrix(). I'm working on a script that imports a skeleton, and the generated bones in Blender must have the same transformation matrix as the imported skeleton (because of animation file compatibility when the skeleton is exported again). H...

Wow, thanks, I use that code for my exporter too and never saw that. Hmm, why does it work anyway? I've never seen that that affects the output. In what cases does it make a difference?

Try this instead:
1234 -> 123 243

Facingness of tris is controlled by ordering of the vertices.
It's just a quick idea, maybe it'll do the trick. Won't be a big deal to change your script to test it...

There are some scripts that do export meshes with skeletal animation. The godfather of them being Jiba's "blender2cal3d" script (I don't have a link, but it was distributed with Blender2.32). I, for example, wrote another script based on this one, for MD5 export (http://www.doom3world.org/doom3/der_...
