This plugin allows you to import .rip files captured with NinjaRipper directly to Autodesk Maya
Copy NinjaRipperMayaImportTools.py file to Documents/Maya/[version]/scripts.
In the same folder create (if not exist) usersetup.mel and add to end:
python("import NinjaRipperMayaImportTools")
Thats it. Next time you launch your Maya you'll see [Ninja Ripper] tab in context menu.
