cannot display a bone animation correctly

I cannot find what is wrong in my codes. bones movement seem like correctly, but positions of vertexes are wrong. if anyone would help me out, leave your email and i will send your my model file. thanks a lot.  


Does your model display correctly in PVRShaman?

yes, and finally i find the answer.

bits of bone weight is too big, GL_BYTE cannot read it correctly.

thx for replying.
