I’m not sure exactly how this got setup, but when I select a fixture, the intensity goes to 100. When I unselect the fixture, it goes to 0. How do I change the mode of the program so that it doesn’t change intensity when I select that fixture.
Likley highlight mode is on. You can go to Tools → Highlight to toggle the mode on or off. This mode is useful when testing fixtures or identifying them but should be off otherwise.
I agree with Ronin, it is likely “Hilight” is selected. On the fixture chooser page look at the soft keys bar. I thinly by default it is the 5th or 6th “Button”. If it is red it is active and any selected fixture will go to 100%. This is very useful when you need to focus a group of movers.
