13.15. Auto-calibrate fixture positions
The Auto-calibration is a system where the software positions moving light fixtures based on four makers on the real
floor. This can work, but you and the fixtures needs to be precise.
One of the big advantages with having a precise position and rotation of your moving lights is the option to use XYZ
position programming.
You can access this system using a
and opening the
Stage View Options
. Here is a tab called
"Calibration". In this tab you will find a single button called
Calibrate Fixture Pos
. Tapping this will open the
Calibration pop-up.
It could look like this:
Calibration pop-up - Absolute Mode
This is separated into a left and a right side.
The left side is used to define the markers on the floor.
The right side has short description of the workflow in this view. There are also four buttons used to control the
calibration function.
The first button is called
Find Alternative Flip Solution
. This can be used to use a different set of Pan/Tilt values to
reach the same point. Moving head fixtures can often hit the same point with up to three different set of values.
When the
Output Stage Values
button is active, then the currently selected fixtures will output the Stage values.
Stage values can be edited in the
, Fixture Types editor and in the Fixture editor.
You can use two different modes for the calibration process. One is called
Absolute Mode
and the other is
Free
Mode
. You can change between the two modes by tapping the Mode button on the right side of the pop-up.
