Hello @Petr Vanek, Thank you for the update. I will update my GDTFs and look forward to this development!

Hello, One of my products is a pan/tilt module where you can mount a stationary light or a mirror module. How does this work in GDTF? I can link a fixture type (of the stationary light) but that appears to do nothing. Is there a possibility that i can include a existing GDTF/model into this GDTF of do i have to create a GDTF for each option?
