Dear All,
i draw a scene in autodesk 3dmax 2012, and export objects to obj file. but when i load it on my app, the origin position of the vertex is like 3dsmax and not zero. how to set the vertex origin to zero, (need minimum vertex pos to zero pos and other translate like it.)

i found it,
i set my object position in 0,0,0 in 3dsmax and export obj file and redo back again object position.
