Live preview is active but
recording is not possible
Enter the subject dimensions: body height and foot size (Section 8.1).
Perform an N-pose calibration (Section 8.2.2). Make sure to apply.
MVN Awinda:
Make sure that no Synchronization settings have been saved to the
Awinda station
Directly after the T-pose
calibration, the axes of
rotation of the subject do not
correspond with 3D
character.
Place MT on the pelvis flat on the sacral bone with Z axis pointing away
from subject.
Magnetic field is too disturbed at calibration. Use the ‘Show Magnetic
Disturbance’ option in the preview window to find a proper location (no
red spots in 3D viewport) (Section 19.2.1).
Character sticks to the
ground or segments are
pulled apart (wrongly
detected contacts).
Enter correct body dimensions of subject (Section 8.1).
Perform new calibration pose.
Choose suitable user scenario (default is flat ground assumption)
(Section 7.2.12).
Make sure the feet trackers are mounted rigidly.
Character appears to
bounce slightly when no
movement is taking place.
This is likely to be caused by visualization rather than data issues.Can
result when tile size on the floor in MVN Studio is large.
Verify that the character is not moving using position data (eg graphical
representation) to ensure that no movement is being detected. The
position data should remain unchanged.
When this is the case, make the tile size smaller, usually 50cm is a
good tile size for visualization. To do this, go to >Options >Preferences
>Interface > 3D View
Shadows have jerky
movements, even when
character remains
unmoving.
Visualization issue, probably caused by floor tile size being too large,
meaning that the shadow is redrawn too frequently. Decrease the size
of the tiles to reduce this visualization effect.
Pelvis is displayed too high.
MVN file is recorded with old version of MVN Studio. Make a copy of
the original file and reprocess (Section 10.3.2.7).
Pelvis is displayed too low.
Use MVN Studio v2.0 or higher to play the MVN file.
The system does not run in
real-time.
Close all other running application.
Check wireless connection (maximum range and disable other
wireless equipment).
Reduce the display frame rate and/or update rate.
