The 1.1.0 beta version of the RawKee plugin is available for Maya
6.0-8.5 on Windows.
New features? Well there aren't really... I added new naming conventions
for HAnim export last spring but I haven't been able to test them yet as
I just got everything to compile and export without crashing on Windows.
Use it at your own risk.

Hopefully, I'll have some linux and OSX builds available soon as well.
