I have edited a fixture (reverse CMY) but after doing so, the control channel commands are gone.
Is there a way to prevent this, or do I have to request a fixture file?
What fixture are you trying to edit? Is it an existing one in our library or is it a new fixture you're creating yourself? The control channels should not go away unless removed from the profile
I changed the Roxx e.show tw+ 14 channel
The CMY parameters are not reversed (its an RGB par) so I reversed them myself. Nothing fancy.
I added a revision and changed the username to my name, then build the fixture to replace the fixtures in the showfile.
I am also experiencing this issue, even when starting a fixture from scratch. The button is gone from the slot toolbar while the function remains in the fixture in fixture builder. I will get this logged into our bug tracking system.
Meanwhile you can log a fixture request on our Fixture Library Hub
