[raft]

you can select Animated3D's in an AnimatedGroup either with index or with name. have a look at AnimatedGroup.get(int/String) methods

what should i do if i want to export multiple mesh ogre to bones?

"jmeOgre2Bones -out bone.bones -in mes1.xml mesh2.xml" like this giving error number of vertices differ

my model in 1 blender file

"jmeOgre2Bones -out bone.bones -in mes1.xml mesh2.xml" is for merging multiple animations into one. that's why the meshes and skeletons should be identical.

(although I didnt use it) you should be able to export multiple meshes from Blender. In 3d Max OgreMax plugin can export multiple meshes.
