Is there an advantage to working in edit mode? I normally use update values by making my changes, right clicking the gear and selecting, "Update values"
Edit Mode is made to add or update any parameter in the selected cue(s), while "Update Values" updates the values of all parameters existing in selected cue(s)
Also, is it possible to have 12 individual groups exist in 12 individual cues?
Sure. But a cue will send values to parameters that are stored in it. So if "Surface Group 1" is not stored in "Cue 2", starting Cue 2 will not make "Surface Group 1" off. What you can to is to:
- make all your surface groups invisible
- select all your cues
- enter Edit Mode
- select all surface groups and press the surface groups "Visible" checkbox
It will make all surface invisible in all selected cues. Then in each cue you switch the corresponding surface group "Visible" (either in Edit Mode, through the cue inspector, or using "Update Values").
