After importing an object ModelConverterX does optimise the scenegraph, the structure of all the nodes in the object, as you can see in the hierarchy editor. During this process the node names that ModelConverterX can read from certain file formats were often lost. After multiple requests from users that they would like to keep those names, for example because it make it easier to edit the MSFS model XML or to find a specific node, I have now modified the optimisation logic so that it will preserve those names.

By default the logic to preserve the node names is off, since it can result in a less optimal model structure and thus more drawcalls. But you enable it in the ObjectModel settings in the Options form. Just set the value PreserveNodeNames to true.
