I have just released a new version of ModelConverterX. Download If you want to check it out directly, see the download details here. Changes Compared to the version 0.55 release there have been loads of improvements and bug fixes. I'll try to list the most important here: The FSX MDL exporter writes transformations and animations correctly. A Level of detail Creator has been added that allows the automatic construction of lower level LODs. The algorithm does not yet work correctly on every object. ModelConverterX does no longer depend on additional libraries to load the textures of objects. The performance of the object preview has been improved. LODs are written by the 3DS and OpenFlight exporter. Transformations are written correctly by the 3DS and OpenFlight exporters. SCASM macros using user variables are supported. Many more small improvements... Feedback I hope you enjoy this new version. Please use this subforum to report any suggestions, comments or bugs.
