You can use the FBXExport command to create the ExportFBXOptions property, and then use either the OM or SetValue to set the FBX options. For example, this Python snippet creates the FBX property by calling FBXExport( “option” ), and then sets the FBX SDK version (for which there is no separate FBXSetExport command).

si = Application
si.FBXExport( "option" )
o = si.Dictionary.GetObject( "ExportFBXOptions" )
o.Parameters( "FBXSDKVersion" ).Value = "FBX201300"

You can do the same thing for FBXImport with FBXImport( “option” ), but I always got an error, even if the property was created.

si = Application

try:
	si.FBXImport( "option" )
except:
	o = si.Dictionary.GetObject( "ImportFBXOptions" )
	
si.LogMessage( o )
