Export MotionBuilder Mocap Data

Walkthrough how to export mocap data from MotionBuilder to create a Style Clone.

Prerequisites

To follow this guide, first you must have:

1. Brought your mocap data into MotionBuilder

2. Retargeted your animations to the Motorica hierarchy

Preparation

Before exporting your animation files, it is highly recommended to plot all animation properties to the Motorica skeleton. This avoids issues caused by improper interpolation, or keyframes that lie outside the take's play range.

1. Select all bones in the Motorica skeleton by right-clicking on Root then Select Branches :

1. Open the plotting tool via Animation > Plot Selected (All Properties) :

1. Plot your animation with the following settings:

• Plot On Frame enabled

• Plot All Takes if you have multiple takes in the same file

• A frame rate of 30, 60 or 120 FPS

• Constant Key Reducer disabled

Exporting

Now that the animation data has been plotted, we are ready to export. For this, we recommend using Motion File Export to ensure you're only sending animation data to Motorica. We must also ensure that each exported file only has one take inside it.

1. Select all bones in the Motorica skeleton by right-clicking on Root then Select Branches :

1. Open the export dialog via File > Motion File Export :

1. Choose your folder and name the files as you wish, but ensure it is an .fbx or .bvh filename:

1. Finally, select all takes you wish to upload to Motorica, with One Take Per File enabled:

And you're done! Following these steps will make the style cloning process simpler, preventing technical issues caused by the FBX file format, allowing you to focus on reviewing the quality of your uploaded data.
