Re: [osg-users] Controlling animations in FBX models
Hi Thomas, I tested your code and I got an error: OsgAnimationTools AnimationSplit XML Config ERROR: AnimationSplit nodes must contain a 'splitCount' property. The function that reads my FPS returns 0, even when I set to 30 in the xml file. Also, the function ReadAniSplitFromConfigNode() has a variable splitCount that is never used. If you can help me, I will be thankful. Renato On Mon, Feb 14, 2011 at 12:22 AM, Renato Silveira silveira@gmail.comwrote: Thank you very mutch! I will check it.

Re: [osg-users] Controlling animations in FBX models
Hi Renato / others
I've finished my animation splitting system, seems to do the job for me. I
used osgDB XmlPaser to allow an xml file to be used for config and have
successfully loaded my original long animation file and split it
into separate 'takes'.
Attached is the cpp and an example config file. I think it's pretty straight
forward.
Let me know if you get stuck
Cheers
Tom

Re: [osg-users] Controlling animations in FBX models
Hi Renato I thought it was not possible. How can you save your FBX file with multiple animations? I'm using 3DS Max 2010 and I do not see a way to save multiple animations. I'm not familiar with modeling ... I need to do something similar at the moment. I know MotionBuilde can export fbx with multiple takes, but 3ds max can not. I plan to write a node visitor that will find and split any osg animations into multiple takes. Perhaps using a config file. Shouldn't take long, I'll send you a copy when I'm done. If you export your fbx from osg as a .osg file you can see how the data is stored and looks petty straight forward to split it. Alternatively you can use MotionBuilder and I know the FBX plugin is capable of loading the multiple takes.
