After a period of some inactivity, here is a new version of ModelConverterX. This are the main improvements: Fixed issues with transformations being applied incorrect Improved reading of API macros with "exotic" code structures Fixed texture mapping problems Improved mif/melse/mend handling Improved speed by updating the log less frequent (only after object reading finished) Made FSX MDL reader a bit more robust Added 3DS exporter functionality For the 3DS export functionality there are still some limitations, but it should export static objects with a material or texture correctly. All the polygons with the same material end up being one part if you import it into 3DS or GMax later on. Also all polygons will be triangulated. But still it could be easier than starting from scratch on your objects. You will also see that the first time you start the tool you will have to accept the user license. I added this to make it clear once more that this tool is meant only to convert objects you are the designer of. Do not use it to convert/edit other people's work without their permission. Quite high on my todo list now is support for LODs, so maybe I can add that in the next version.
