I have made some updates to ModelConverterX today. These are the main changes:

• Fixed some issues with exporting animations to the FSX MDL format. Sometimes some animations were missing after exporting, this should be solved now.
• Improved the part of the MDL reader that reads the custom variables used in aircraft MDL files. These should now be read better and I have also expended the list of known variables, so that more of them should have a meaningful name now. Only for old FS98 MDL files the names seem not correct yet, I will work on that.
• Fixed a bug that caused some animated parts to get a wrong offset after reading.

All of these changes are available in the development release from tomorrow. I hope that you will see that more aircraft MDL files can now be imported correctly and converted to static scenery objects.
