How to use motion capture data in 3D Studio Max with Character Studio

1.Click on the create panel.

   
 
2.Click on system and biped.

       
 
 
 
3.Click and drag in a viewport to create a biped.


       
 
4.Click on the motion panel.

       
 

5.Open the motion capture section.

       
 

6.Click on the icon with the folder and camera, to load a motion capture file.

 

7.Select a file to load and open it.

 
 

**You may get a warning that some of the markers were not recognized. Character studio uses all of the markers that are used for the motion capture. The warning is just letting you know that the data from the listed markers will not be used on the biped.



8.Click ok in the motion capture conversion parameters to accept the default settings.

 
**We recommend manual key reduction of motion capture data. However this panel will allow character studio to automatically perform key reduction of the data.

9.Click play to view your motion capture data.

Key Frame Reduction
Key frame reduction is important for game animation in order to save memory. There is built key reduce that you can use when importing a motion file. However best results are achieved by reducing keys by hand.

1. Start with the Bip 01 and work your way down the Biped hierarchy. Scroll through the animation and look for the changes in direction on the bone you are studying. This is where you will want to keep a keyframe present. The keys where there is not a change in direction can be deleted. As you remove keys check to see how the animation looks, make sure that you didn't remove to many keys.


 

2. Turning on the trajectories will help you visualize these direction changes and where keyframes will need to remain. This is done under the "Motion Panel".

 

3. After Bip 01 I would next reduce the Pelvis and then the Feet. If the character isn't moving their feet then just delete the feet keys, making sure to leave 1 key at frame 1 which you can use to lock the feet down using the "Key Info" rollout in the "Motion Panel". Otherwise follow the same process as with Bip 01. After cleaning the legs work on the arms and the rest of the skeleton.
