m2u (Max/Maya to UDK) is a python script for Maya and 3dsMax to sync input to the UDK editor. It is still work in progress, but a first beta version has been released for testing and collecting feedback.
We started it as a student project over a year ago but due to much other stuff going on we never came to actually working on it. Now we had to hand something in and while programming just enough to pass our project, we came to the point where it actually started functioning like we planned. So we are now still developing it further and will continue to implement new features and publish new beta releases for public testing every now and then.
Here are some preview videos and if you want some more technical information, you can check out my post over at polycount.com.
