The 8 byte data block looks like a quaternion stored as 4 signed 16 bit integers (divide by 32767 to get the quat). From your sample: XYZ Euler angles in degrees [180 -9.457 180] is XYZW quaternion [0.0000 0.9...

Well done, Zashibu. Thanks for the update.

Just simple logger nothing special It's special for us who are not familiar with this type of work :) However, I did follow your tip with a small amount of homework for the .gfx data with excellent results, thank you :) I'm not familiar with logging file names from an executable, either.
