FBXGetTakeReferenceTimeSpan [index];
Returns the reference start and stop times of the take at the specified index in the take array. This command uses the file
stored in the file buffer.
You can load a file into the file buffer with the command.
Note
You must enter numbers from 1 to the number of takes contained in the file, otherwise the script returns the message: . The Maya FBX plug-in considers any number of takes greater than the amount of takes in the file, negative values, or zero, to be invalid.
