its only IPI to source engine SMD that this problem exists
This looks very much like a bug related to Advanced Motion Transfer. For your information, by default Advanced Motion Transfer is turned on for SMD export because normally SMD model skeleton is different from default iPi skeleton and motion transfer is required. By contrast, exporting your animation in MotionBuilder-compatible or 3DMAX-compatible format does not involve motion transfer (since skeleton is essentially the same).
Turning off Advanced Motion Transfer may help. Also, please make sure that you use latest version of iPiStudio (1.2.0.118).
