+===== Create Control Rig =====
+We do not key joints directly. We key curves/controls in order to fix mocap problems. So we create a custom control rig:
+   - Unlock the Character Definition by clicking on the lock in Human IK.
+   - Click on "Create Custom Rig Mapping" in Human IK.
+   - By default, it assign ankles and hips.
+   - Connect controllers to the control rig by select the controller and right click on coressponding control rig point and "Assign selected Effector".
+   - Disconnect the translation on the head (deactivate Map Translation).
-If the green checkmark is displayed, everything is ready.

-If you do a new scene, you can import then this character defintion so you don't have to do it once again.

-===== Control Rig =====
-We need a control rig. In Maya not key joints directly. We key curves/controls, order to fix mocap problems.
-Click on "Create Custom Rig Mapping" in Human IK. By default, it assign ankles and Hips.
-Connect controllers to the control rig by select the controller and right click on coressponding control rig point and "Assign selected Effector".
-Disconnect the translation on the head (deactivate Map Translation).
 ===== Import Mocap Data =====
-File > Import and choose FBX
+In order to import motion capture data, you need to [[motive_takeexport|export the correct format (FBX Binary) in motive]]. Choose File > Import and import the motive FBX binary file.
-Also the mocap data has to be characterized.
-Grab all Joints and set rotation to 0 (in channel box).
-Select Hip and set x=0 and z=0.
-Select Hips and move y so that character stands on ground.
-Open Human IK and klick Create Character Defintion.
-Rename Charackter to "Mocap"
-Assign all bones from mocap Skeleton to Character by selecting bone in Sekelton and right click on Character "Assign Selected Bone". For Hip and Neck use lowest joint.
-Save Skeleton Definition. No need to change prefix. Change Location to your maya project. Change Template name to "mocap_CD".
-In Human IK, select Character your Character, and on Source select the Mocap Character.
-Select the pole vector and set it to follow (10) in channel display.
-You need to Bake the Mocap Animation to the Human IK skeleton:
+Also the mocap data has to be characterized:
-Human IK > Bake > Bake Custom Rig
+  - Grab all Joints of the mocap
+  - Open channel box and set Rotate X,Y,Z=0
+  - Select Hip joint and set Translate X=0 and Z=0
+  - Select Hips and Translate Y until the that character stands on the ground
+  - Open Human IK and click Create Character Defintion
+  - Rename the character to "Mocap"
+  - Assign all bones from mocap skeleton to character by selecting bone in skeleton and right click on character "Assign Selected Bone".
+  - Save Skeleton Definition. There is no need to change the prefix. Change to location to your maya project. Change Template name to "mocap_CD".
+  - In Human IK, select the character the character to animate, and select as source the mocap character.
+  - Select the pole vector and set it to follow (10) in channel display.
+  - You need to bake the mocap animation to the Human IK skeleton: Human IK > Bake > Bake Custom Rig
 After that, you can start clean the Mocap Data.
