It took me roughly 2.5 years to understand and watch closely how light operators usually work with fixtures. It is since 2024 where I needed desperately a way to acquire fixtures data in a solid and well formatted way in vvvv instead of going every single time checking the spreadsheets and trying to map the values on my end.
It is just a couple of days maybe weeks, where I updated VL.GDTF (it is not publicly available as I am writing this post). After discussing it a bit with @joreg and @ravazquez I decided to proceed with my simplistic and quite stupid approach (KISS) where all the logical channels are exposed, this obviously adds a lot of noise and in some complex fixtures you may see way more than 40+ inputs which can be s bit intimidating and obviously ugly.
However it is quite satisfying for my needs and I will gladly share it as soon as it becomes a bit more polished and organized.
The idea is to put your GDTF files in a specified folder called “fixtures” next to your VL patch and call either an instance (a gdtf fixture) or its definition if you want to map attributes and channels on your own.
here is a snippet:
