 +===== Import Character Model =====
  
-===== Import Character =====+   - Model your character in T-Pose and not Y-Pose to connect the mocap data. 
 +   - File > Create Reference... and choose model file and namespace to link to. Set a short namespace, which is important for import/export.

-A referenced Character has a Namespace which will be important for import/export. 
-Use short namespaces. 
-Namespace change: Windows ... > Namespaces

-Windows > Animation Editor > HumanIK+  - Display HumanIK: Windows > Animation Editors > HumanIK 
 +  - In HumanIK click on Create Character Definition 
 +  - Rename Character by clicking on the blue icon > Rename Character 
 +  - Map Joints from Outliner to HumanIK (map only main joints, part joints not need to be mapped) by: 
 +    - Select Joint in Outliner 
 +    - Right click on corresponding joint in HumanIK Character Definition and select Assign Selected Bone 
 +    - Map Root in Outliner is the Hip in Character Definition 
 +    - Map Chest to the first Spine (Spine1) 
 +    - Map Neck the first neck (Neck) joint 
 +    - Go on with all other Joints. 
 +  - If the green checkmark is displayed, everything is OK. The character will get orange if there is a problem. 
 +  - Save Skeleton Defintion at the end by clicking on floppy disk symbol at HumanIK window. 
 +  - The prefix of the skeleton defintion needs to be changed since we use a reference. If we import the mocap data, there will be a Namespace (name of the Character in Motive). Delete the "Root" of of the prefix but leave the ":". Change the path to the "data" location in your maya project.

-Map Root in Outliner is the Hip in Character by click in Outline the Hip and Rightclick on Hip in Character > Assigned selected Bone.+Remarks:  
 +  * Map Shoulder does not work if character is not in T-Pose. Rotate Arms so that the Model is in T-Pose until character switches to green. 
 +  * Also the feets must be parallel to the Z Axis.  
 +  * If you change the model, make sure to clear the assignment data before reassigning the bon it to refresh the offsets. The offsets are calculated when you assign the bones. 
 +  * If you create a new scene, you can import the saved skeleton defintion so you don't have to do it once again.
  
-Map Shoulder does not work if character is not in T-Pose. The character will get orange if there is a problem. 
-Rotate Arms so that the Model is in T-Pose. The character part will switch to green if it can be mapped correctly. 
  
-Also the feed must be parallel to the Z Axis. If you change the model, make clear the assign data before reassign it to refresh de offsets (the offsets are calculated when you Assign the bones).+===== Create Control Rig =====
  
-At thte first Spine (Spine1) apply the Chest. +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. 
-At the first neck (Neck) apply the Neck. +   - Click on "Create Custom Rig Mapping" in Human IK. 
- +   - By default, it assign ankles and hips. 
-Go on with all other Joints. +   - 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. +
- +
-Save Skeleton Defintion at the end by klicking Floppy at IK Window: +
-The prefix needs to be changed since we use a Reference. If we Iimport the Mocap Data, there will be a Namespace (name of the Character in Motive). Delete the "Root" of of the prefix but leave ":". Change the path to the "data" location in your maya project. +

-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. +
