One of the features on the ModelConverterX wishlist is adding support for writing FSDS FSC files. I can now say that I started working on this. I got a SDK from Louis Sinclair, the author of FSDS, that explains how the file format works. To get more used to the format I decided to first make a reader that can import FSC files. The current development release has an initial version of this reader included already. It should read the geometry correctly, but I am still working on animations and other advanced features. I think I’ll also need some more test files to test the reader on those aspects. After the reader is done, I will start with the writer.
That I started on this FSDS support does not mean that the FS2004 MDL reader is completely done, I still have to look at the attachpoints and figure out a way to deal with the conditions and LODs. These issues are still high on my todo list as well and if there is feedback on how the FS2004 MDL reader works with your animations I would also like to now.
