I can't help about data, all data i used was exporter from the blender exporter, an example of what you can do with osgAnimation is on this live stream http://stream.pok.me/stream.ogg You can have a look to the source code here http://hg.plopbyte.net/pokme/ > > Finally, osganimationhardware nathan.osg is giving me problems.

Yes hardware should improve, not that for small skinned mesh, it does not help at all. I will have a look at that crash this evening. > > Thanks in advance, > > J-S Cedric - -- Provide OpenGL services around OpenSceneGraph and more +33 659 598 614 Cedric Pinson mailto:cedric.pin...@plopbyte.net http://www.plopbyte.net -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.14 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkuiYCEACgkQs6ZHzVQN0Ii7LwCggAwBfZGVLIAYLXZDB6gFam7R mo4AniU1KoMgrJy7FoUZbQ1xyFerbe5J =L0rF -----END PGP SIGNATURE-----
