Hello

In Unity, i’ve placed a cube over a section of the map with the Studio Parameter Trigger (Script) component. I’ve set some music to fade in upon entering the trigger zone, which it does.

**How can the music be disabled when exiting trigger area?**

I know i could place several other cubes around this first cube with ‘Trigger exit’ as the parameter trigger scripts trigger option but this seems tedious. Surely there is an easier way ?

If it is the same trigger zone, you could just add another Studio Parameter Trigger to the object that uses Trigger Exit.
