Aligning to Source

Motion Live provides feature to align the stride to the real actor, neglecting the 3D character's proportions or height in order to meet your needs and scenarios.

1. Apply characters of different proportions.
   
2. Mocap the body performances. As you can see the motions will retarget automatically for the characters to ensure the corrections.
   
3. However, the other character will fail to reach the correct position due to its smaller frame.
   
4. Select one of the character, activate the Align to source checkbox on the Motion Live panel to match the positions for the characters.
   
   Mesh Penetration after Align to Source is Activated:

   After the Align to source is activated, the foot sliding or mesh penetration issues may occur. These issues can be addressed with an additional technique: Foot Contact feature. Simply activate the feature in the Modify panel to prevent the feet from sinking.
   

5. Start mocapping again. As you can see the characters' motions are forced to align to the real performer, especially the position.
   
6. After the motion has been captured as a clip, use the Motion Correction feature in iClone to fix up the foot sliding issue.
