The Lighting Controller II

Just a question; can someone explain what this button does? Tried it on multiple functions but can’t see anything happening

Thank you!

Please do that in module Generator:
- select the tab "Fixture"
- select the first fixture from the list and move its point somewhere
- select the last fixture from the list and move its point in another location
- right click the point and select the menu "fan point"
Then you will see the point of the other fixtures spreading from the first point to the last one.

PS: there is an explanation for that in the User Guide at page 31, but it may be not clear enough. So we will update it with more details.
