ogrexmlconverter - error in skeleton conersion

[subha27]

Hi All,

My animation designer is using Maya and she has send me the mesh and skeleton file for testing,

I am getting following error while converting the skeleton file to xml,

lod levels = none (or use existing)
Generate edge lists = 1
Generate tangents = 0
semantic = TANGENT
parity = 0
split mirror = 0
split rotated = 0
Reorganise vertex buffers = 1
Optimise animations = 1

Please let me know when this error can occur ? Is anything my animation designer should take care while exporting the file from Maya ?
