Mass material import/export V0.1
I hope some people will find this useful. This will import a folder full of .mat files into your scene so you can convert them and will then save them out back into individual mat files.
Run the script. press import. locate your mats folder.
It will import them all into the scene and apply them to small boxes.
The corona converter will open.
Convert as necessary and then click export.
Choose your export folder. It will save out with the original name and a '_crn' suffix.
If you have an older version of the converter (1.29) open the script in notepad and find the line at the bottom referencing the converter and just change your version in the string.
Let me know if you have any issues.
Enjoy!
