Vicon Evoke 1.5 resolves a number of issues, including the selection listed here:

• Evoke no longer occasionally stops responding when updating the object tracking state.
• Calibration objects are now always assumed to have their up-axis aligned with the Z-axis, rather than setting perpendicular to the largest plane on the object.
• Fixed workspace Cameras view does not not revert to showing all cameras after the selected camera is removed.
• Character names are now displayed in the 3D Scene workspace view.
• Character Not calibrated warning now isn't shown if Disable Solving is selected in the Processing panel.
