Been asked for help by Neasa, so I thought I'd blog it here, it would be nice for others too, mind you this is super vague and I'm not an expert so I'm just showing how I went about it.
Video Tutorials on Maya to Motion Part 1, Part 2 from adachan1 on youtube.
Firstly, you need to have your animation data from ViconIQ, in .c3d format- or fbx if you've already messed about with it. You need Maya 2012 if you want to import/export it easily like I did. Also this tutorial uses the skeleton generated by the MotionBuilder characterisation plugin in maya. So if you have a custom skeleton, I can't help you too much with that.
Open up your MotionBuilder, and for your sake, set the keyboard configuration to 'Maya' so you won't have to relearn all the controls again for MotionBuilder. This means things like the move, scale and rotate tools are all asigned to the same 'W, E, R' keys. Settings > Keyboard Configuration > Maya
Importing your Animation Data
In the Asset Browser tab under the 'Resources' area, you can selet useful files here like the Actor dummy. I added a file directory containing all my animation data, so it was easy for me to access. Right click > Add favourite path. You won't regret it.
So with your folder added, you can quickly select your files through this browser. Click and drag the file over, select the 'Import' option.
