hard to say someting certain from that stack trace. try some other Ogre viewer and see if that successfully loads your model. if you cant find a viewer (dont know your platform) you can also use ogre command line tools (OgreXMLConverter or OgreMeshUpgrader) to see if your file is valid

Thank you for reply! I convert xml to .mesh by OgreXmlConverter (from tools), it show  "WARNING: vertex count (9900) is not as claimed (1788)", i don't know why, but now i change <sharedgeometry vertexcount="9900"> in XML and try run :

Code: [Select]
Exception in thread "main" java.lang.IllegalArgumentException: No controller found in OgreEntityNode. Means there is no skeleton or pose animation!

that means there is no animation in your xml file as the exceptions says ;)

btw, if that exporter even writes vertex count false, i wouldn't trust it much..

I reexport model with animation, change manually vertex count again, after that found null pointer in SkinHelper.asArray(mesh.getTextureCoords().get(0).coords)  (BonesImporter.class) - 0-key value some reason was null, get(1) ... and finally i saw model on screen... but as 1 mesh without submeshes. So i hope next release will be better.
But now i solved the problem in next way - bender 2.57 -> collada .dae -> blender 2.49 (with it ogre exporter) -> create bones etc -> make animation actions/ shape keys -> export to ogre mesh  ;D

if i get you correct you use collada to export from blender 2.57 to 2.49, right? why is that, 2.49 works better than 2.57?

anyway, if it works that way ;)

For 2.49 exporter work good.  Model was made in 2.57, when i try open it in 2.49 blender crash, so i mast use intermediate format for import model to 2.49
