Offical EM's Naiad Buddy for Arnold can't fit my requirements, so I wrote a procedural to load .emp cache file and generate AR's node directly.
All code could be checked out at Ortholab/NtoA.
WARNING:
I have just recieved the mail from AR's author Marcos Fajardo, this NtoA is "in conflict with the non-disclosure agreement", so I will clear NtoA at Ortholab. If you have more questions, you may contact with me.
