Fixture calibration data can be saved as a calibration file separate from the BlackTrax project. Calibration can be saved as a BlackTrax Calibration file (.btcal) which can be read by BlackTrax, or as an XML file for third-party use. Calibration profiles saved as .btcal files can be loaded and edited as needed in a project.

• Fixture calibration data from any preset can be exported or imported into any preset you are currently in.
• The calibration data that was imported becomes part of the preset you are currently in.
• The calibration data that was imported remains part of any other presets where data has been exported from or into already.

Attention: BlackTrax cannot use XML calibration files to further calibrate fixtures. Fixture calibration saved to this format is only for third party use.

To export calibration data

Created calibration data can be saved separately from the BlackTrax project as a BlackTrax calibration file (.btcal).

1. In Fixture Calibration View, ensure that you are currently in the preset that you want to export from.
2. From the File menu, choose Export and then choose Fixture Calibration. 
   •    Export Calibration Menu
   • Result: The Export Calibration browse window appears.
3. In the Export Calibration window, select which calibration file type will be used from the drop-down menu.
   • Note: To export specific fixtures from a preset, select the desired fixtures before exporting your calibration data.
4. Navigate to the location where you want to save the calibration file.
5. In the File Name field, type the name of the calibration session.
6. Click Save.
   • Result: Information on all fixtures (calibrated or not) are saved to the calibration file. The information will be accurate so long as the calibrated fixtures are not moved or bumped. This is provided the Motive calibration is the same (relative to the origin).
