Hi, I have improved the FS2004 MDL reader a bit more. I solved some problems with reading the transformations that caused crashes when loading some of the default library BGL files. Now they load fine, but I noticed that some objects show as empty. This is because these have an empty LOD as their first LOD. Currently ModelConverterX can not yet read the LOD structure from these files. I think I might try to read the highest LOD only for the moment, or find another way to address this.
