Quick facts:
For an .fbx file that you want to convert to an .skm, simply drag and drop your .fbx file to the FbxToSbmConverter.exe and a .skm with the name name as the .fbx will be output in the same folder as the .fbx
Paste the following line in the newly created .bat file
FbxConverter.exe someFbxFileName.fbx output .sk
The FbxToSbmConverter uses the node prefixed with "AnmDef_" to read the sync point data. On this node, the property "SmartbodySynchPoints" is searched for.
If it exists, then a comma separated string of sync named is parsed and output wit their associated sync point data. If that property is not there, then the following
old-style sync points are output: ready time, strokeStart time, emphasis time, stroke time, relax time
