pod file export from maya

hi, everyone.
    when i test my pod file exported from maya, using sourcecode of skinning in the training courses. I add light data myself, the model display strangely.
    part of the animation can show correctly, but some are not. it seems like some points do not move with the bones.
    the pod file can display well with pvrshaman of windows version, but my working environment is linux, it can not display well.
    confusing for 3 days…
