Controlling Zoom and Iris
Zoom and Iris can be controlled from the Fixture Calibration Control widget using the Zoom and Iris
sliders similar to pan and tilt of the selected fixture(s). If the checkboxes for Apply Globally are set, then
the control will apply to all currently active or queued fixtures, otherwise, it will only apply to the
currently selected fixture.
Note: A momentary loss of control of your fixtures will happen occasionally while changing the
Zoom and Iris in Fixture Calibration mode. This normal behavior happens only when you use the
sliders to actively control the Zoom and Iris in Fixture Calibration mode.
Clearing Colour and Gobos, and
Controlling Intensity
BlackTrax will also attempt to auto clear any colour and gobos that the console is instructing the fixture
to use. While in Fixture Calibration Mode, BlackTrax will also control the intensity of the fixtures, turning
them on or off based on if they are queued or not.
