GDTF 1.0 Plugin
GDTF stands for General Device Type Format. The file format was originally conceived and jointly developed by MA Lighting, Robe and Vectorworks to be an open standards technology. Manufacturers involved in the entertainment design, production, and performance industry are welcomed to participate in supporting GDTF.
Since many manufacturers won't ever provide their fixture definitions in GDTF and many lighting programs (including legacy ones) won't ever understand them, the Open Fixture Library with this plugin is still needed ;)
