Hi all,

been searching through the forums and see some similar problems, but the only one similar to my issue is the 4 bones per vertex, and dont know how to fix that xD can someone please give me some solution or advice?

sorry for my bad english :frowning:

Thanks so much

EDIT:
forgot to mention that I applied all transforms and rotations on armature and model, set origins to 0,0,0, and updated the sdk just this morning.

How many bones are you using? we only support 256

just an old simple an bad model xD, doesnt work for me, but if you delete armature and vertex groups just works, can anyone help?

Also from mediafire: http://www.mediafire.com/download/aawcmpk30kezq21/character.blend

You’ll have issue anyway with the blender loader and skeletal animations, because all the constraint types are not yet supported.
I suggest you try with the ogre exporter.

I tried but dont really get anything, downloaded 2 exporters and both two gave me errors xD

Any “official” exporter or advice?

thanks

Try moving the ogre addon to the blender scripts folder file manually. installing the ogre addon from jme 3 simply creates an ogre file in a folder you selected it,if you cant find you can download it from internet

Plus ive been exporting ogre meshes from blender 2.67
