I have just put the first version of the Animation Tweaker in the ModelConverterX development release. You will find it in the Wizards menu. This first version can do two things (or actually it does those two automatically to all files you process with it):
- Make FS2004 animations with more than 1024 frames
- Update the animation to use local variables
As input to the wizard you should use FSX MDL files. I did test this new function with some test files here, but please let me know if you have issues with your files. It is a first beta, so might be a little buggy.
