GUID Not Reading (and ?Not changeable) on one particular library bgl I am reading in an FSX object library made of similar objects. Unfortunately, when they were compiled, it seems that duplicate friendly names have been used. This doesn;t seem to present a problem to FSX ... as the GUIDs are unique. Modelconverter does not seem to be able to read the GUID from each object in this case. I checked the original library with SDE to see what the GUIDs are, and they are all unique. Strangely, Modelconverter lists a GUID that is not present in the entire library for each type of object. The only unusual thing I can see about this library is the duplicate friendly names. Also: When I change the GUID and Friendly names in MCX, it doesn't seem to change within the exported MDL file.
