If you want moving fixtures to follow a Trackable, you must place and hang the moving fixtures in BTWYG. When a moving fixture is placed in BTWYG, BlackTrax collects valuable fixture information such as the properties, range of capabilities, orientation and position in the venue.

Moving fixtures must be placed on the floor or hung onto pipes or trusses. The position and orientation of the fixtures in BTWYG must match their location in the actual Space for tracking to work correctly.

Attention:

• Calibration can resolve the fixtures' incorrect locations or backward orientation, but the calibration process is tedious. The fixtures in the actual Space should match their virtual fixture orientation and location to make calibration easier.
• Library objects that are classified as moving lights are capable of following Trackables.

Tip: To keep fixture orientation consistent, make a note on the orientation of the fixture’s tail. This provides an accurate indication of the fixture's orientation.

Note: Read the WYSIWYG Reference Guide’s chapter on Hanging and focusing fixtures for a complete understanding on how to hang fixtures.
