Author Topic: Blender Collada export  (Read 1071 times)

Hi, 

I'm trying to export an animation from Blender. I'm a little confused though, is this actually supported? I've baked the animation (IK) I have, and it appears as a series of frames, but still when I export nothing plays in the flare 3d player (and the _daeAnimation property is empty in the debugger).

Any ideas what I might be doing wrong?

Cheers

Sorry, I suppose a sample file and a few more details are in order :-)

These are the blend files pre and post bake. I'm using Blender 2.63

After doing some research I've found that one of the issues seems to be in the upgrade from 2.49 -> 2.63a the 'bake matrices' option of the collada export was lost somewhere along the way. There is only the built-in File->Export->Collada option now and it doesn't have bake matrices.

Is this correct? Will export of collada from the latest version of Blender just not work?

Hi John,

Unfortunately, Flare3D requires that setting to correctly import collada models. I'm not really sure what was the rationale for removing this setting from the exporter but, yes, at the moment there doesn't seem to be any way to export a Flare3D-compatible collada model from Blender.

We're investigating possible solutions, but we can't promise anything for the immediate future, sorry for the bad news :(

ok, that's disappointing

after a little more research, I found this about the 'Second Life' option when exporting collada: 
http://blenderartists.org/forum/showthread.php?254619-COLLADA-Improvements-for-GSoC
(it's the second last comment, basically says that it is baked matrices)

Do you have a sample blend file that at one point worked?

Guy's I made a Addon for blender to export for Flare3D.
This addon export a collada and if you hace bones and animations, automaticaly bake it. Don't work with Actions, you must to do all animations in one timeline like 3dsMax.
You can download this addon from here: http://www.pudupuduestudio.com.ar/ExportFlare.py.zip
I hope this addon help you. If you have questions, please wrote me at juan@pudupuduestudio.com.ar

Guy's
I thiks the addon work only with flare3d studio. My addon export a .dae then you must to open it in flare studio and save as .f3d. Some guy wrote me and tell me the .dae don't work when you try to load by code. But im not sure. if you can test the .dae will be great!
Sorry about my english.

I just tested it and you're right, it doesn't load correctly. We'll look into this issue, thanks for the heads up.

Regards,

Are there any more updates on this add-on? We're trying to export a simple animation from blender and when we import it in flare3D we cannot see any frames in the timeline or hierarchy.

Hi,

I'm not sure what the add-on does, but we are aware of a pretty important missing feature of Flare3D's ColladaLoader class: It doesn't support curve-based interpolations. Like most things in COLLADA, there are a few different ways of storing animations. We currently support the "baked matrices" approach that according to the COLLADA spec, all exporters should have as an option, but alas, Blender doesn't support in the 2.5+ versions.

I was able to add this feature to our loader but it isn't ready yet for public consumption. I think we'll be able to release it pretty soon. I'm sorry it's taking so long, but even getting this far was a real pain in the neck :(

Cheers,

Haha, that's ok. Thanks a lot for the information.

Sorry for the double post, but when do you think the feature will be out? Less than 1 month or..?

Thanks.
