warnings are not important, nevermind about them.

about the exception, strange, jPCT typically throws it when indexed geometry has missing vertices.

which 3d editor and Ogre3D exporter do you use?

try playing with exporter options. if possible try disabling indexed geometry. if none helps send me your xml files and let me have a look..

[kiffa]

Thanks!

I used OgreMax to export mesh.xml from Maya2012,  first i tried to export a simple (Skeleton)animated mesh without pose animation, and all was ok(export xml -> convert to .bones -> run on phone).

Then i tried to export a complex  dog mesh with pose animation and morph animation, my settings is like this: object settings -> mesh animation -> mesh animation type -> Skeleton + pose， add mesh animation -> track -> skin(threre are 3 options: object、skin、shape, i don't know how to choose...), when i exported,  an error happed, i get the skeleton.xml without animation info( null <animations />). Here was the log:

// Warning: Could not reach pose on CZ_scens09:dog_rigging_finshed_ok:global_Move translate, rotate. //

So i changed my exporter to OgreExpoter, which didn't report error and  i get the skeleton.xml with animation info, but when i tried to convert it to .bones, error happend.

How can i send my xml to you? Please give me your email addr. And what should i send to you? Only a skeleton.xml or skeleton.xml + mesh.xml?

Many thanks!   

[raft]

I've sent you PM my email address. send please both skeleton.xml and mesh.xml.

strange, I was more than happy with OgreMax for 3dsMax. I would expect same performance from OgreMax for Maya.

[kiffa]

I will send xml to you soon, and i found some warning from maya when expoted mesh:

Writing mesh binary...
WARNING: the mesh 'mayaExport' includes vertices with more than 4 bone assignments. The lowest weighted assignments beyond this limit have been removed, so your animation may look slightly different. To eliminate this, reduce the number of bone assignments per vertex on your mesh to 4.

WARNING: the mesh 'mayaExport' includes vertices without bone assignments. Those vertices will transform to wrong position when skeletal animation enabled. To eliminate this, assign at least one bone assignment per vertex on your mesh.

[kiffa]

I've sent an email with xml to you, thanks!

[raft]

well, strange indeed. let Egon have a look at that
http://www.jpct.net/forum2/index.php/topic,2862.0.html

[raft]

is there an exporter option like "use shared geometry"? if so please try disabling it..

[kiffa]

I had modified the model、the skin and the animation，and  exported them by using OgreExporter from maya, and succeed to convert it to .bones.
But when i run it, crash happened.

[raft]

I've seen that the first time. looking at the code, this is most possibly caused by invalid exported data, ie: exporter's fault.

I would suggest using OgreMax

[kiffa]

I tried OgreMax, but it couldn't export skeleton animation info. I don't know why.

I made blend-shape animation and skeleton animation, and i exported them with adding 2 mesh-animation(one is skin-ani, the other is shape-ani), but there were only pose-animation-info in .mesh.xml, no skeleton-animation-info in .skeleton.xml.

[raft]

you can ask for that in Ogre3D forums.

I used OgreMax with 3dsMax and was quite happy with it. I would expect same performance from OgreMax for Maya
