There are many reasons why your data may not pre-process correctly (e.g. you animation doesn’t have root motion, or your animation is oriented incorrectly) so it is vital to preview and visualize the data after pre-processing.
The Motion Data Editor allows several types of visualization to assist with this
Animation Trajectory
This visualization can be viewed without even pre-processing. It displays a green line on the ground showing the trajectory of the entire animation. If you scrub or play the animation, the character should move along this trajectory.
To toggle this visualization on and off click on ‘Show’ in the top left of the viewport and choose ‘Show Trajectory’
Matched Bones & Root Bone
This visualization can also be displayed without pre-processing. It shows two things:
Root Bone Pivot - the location of the root bone in the current frame
Match Bones - highlighted by yellow balls are the bones that are to be matched
Note: The match bones highlighted by this visualization are not displaying pose data. They are simply highlighting the matched bones specified in the Motion Config asset.
To toggle these visualizations on and off, click on ‘Show’ in the top left of the viewport and choose ‘Show Match Bones’ and ‘Show Pivot’.
Pose Data Visualization
Visualizing pose data is very important following pre-process as it is the only way to confirm that the pre-processing worked correctly on your animations. This will only be displayed if the motion data has been pre-processed.
To toggle these visualizations on and off, click on ‘Show’ in the top left of the viewport and choose ‘Show Pose Data’
Blue Balls - Indicates match bone positions recorded for the current pose
Blue Arrows - Indicates match bone velocity at the current pose
Red Balls - Trajectory points past and future
Red Arrows - Character facing angle at each point on the trajectory.
General Pose Data
General pose data is displayed in the top left corner of the viewport. This data is self explanatory:
