Maybe this should be in tips and tricks, but how this kind of situation is solved? I have for example 8 groups, which have different amount of PAR and I want fan offset between groups, not single PARs
Fanning with Grouping and Buddying is amazingly powerful and can truly speed up your programming if you can wrap your brain around everything it can do.
Just don't forget to turn them off when you're done. I can't tell you how many times I've tried to fan something and been surprised by the results because I'd forgotten that I still had Grouping and Buddying turned on.
