So, you want to make that MLTD machinima you're dreaming of, but found that MLTD models is tougher to deal with than you expect? Fear not, because if you use Blender, you can use the scripts in this repository to (hopefully) ease you on managing that MLTD models!
The scripts are written and tested with Blender 2.91, so Blender 2.8 or above should work well. I can't guarantee for Blender 2.79 or below, though.
As of now, the scripts are came in the form of user scripts, not add-on, therefore you don't have to install the script through Blender's add-on manager. To use the script(s) in your project, simply copy one of the Python code included in the Scripts folder to your Blender's Scripts tab, and run the script.
First, make sure that you copied the code correctly. Failing to do so will render the script useless. However, if you have copied it correctly, but still getting error, file an issue to me. You can also fix the error yourself, and file a pull request from your fork.
