Any _raw entry should also include what the units are after application of offset and scale. Or you could just add this as more info to the in_rot_raw block as an extra sentence explaining that they are euler angles. That will lose the 'KernelVersion' information but honestly I'm not sure we care that much about that. Jonathan
