Introduction: UPDATED: How to Use Mocap Files in Maya, BVH or FBX
For those with an FBX file, skip to the next step.
This tutorial is made for Maya 2013, but I believe it should work in 2010-2015.
Since many users were having difficulty using the fbx converter from Autodesk, I've found another method. This method is actually better, I believe, since it runs natively in Maya as a small script file which takes up less room and improves workflow. The python file is an attachment on the instructable. To install put the py file into your Maya script directory (documents/maya/scripts). Now open up Maya and at the bottom of your window there will be a text entry field. To the left of that it will say either MEL or Python. If it says MEL, click on the words MEL. Now copy paste the following into the text field
Now you can hit enter to run the script once, or preferably highlight the text you pasted and middle mouse click and drag the text onto a shelf of your choice at the top such as the animation shelf for quick access.
Motionbuilder also works to convert the files using the file>motion file import and then exporting it as fbx.

Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Import the FBX to Maya
For those using an fbx file, first make sure that the Maya fbx importer plugin is loaded by going to WINDOW->SETTINGS/PREFERENCES->PLUG-IN MANAGER and checking the box to load the fbx importer (for me it is called fbx Maya).
For those with the importer script simply click on the shelf icon you created or enter the command into Maya. Browse to the file and enter the appropriate information for your rig. (default should work)
Step 2: Define Skeleton
Now, import your fbx file using FILE->IMPORT.
Once your fbx is loaded, go to the animation menu set and then select SKELETON->HUMAN IK
Step 3: Assign Joints
Now, in the character panel navigate to the definition tab and select a joint and then select it's corresponding joint on your rig. Now right click on the joint in the character panel and select assign selected joint. Do this until you have all of corresponding joints from your rig mapped out.
Repeat the procedure of defining a skeleton and then mapping out the joints with the motion capture character skeleton.
Step 4: Make the Fbx Drive the Main Rig
Now in the character panel, simply select your control rig in the character drop down menu and then select your motion capture rig in the source dropdown menu.
If you did everything correctly, when you press play your character should move the same as the motion capture rig.
Hope you guys enjoyed this quick and easy tutorial! Share any cool animations that you make with this!
