I've created this repository some time ago, with the intention to house import/export scripts for both the MD3 and MDR formats and collect information about them so those scripts could be fixed and have their missing functionality readded.
There are no MDR scripts yet! We need to develop something using the info we already have (and, if possible, gather even more info). So any kind of help is welcome.
