Well, I do have a question.
I tried to add one tile (the 2x2 with single "can" light) and sort of got it to work.
I tried to add a compose of it to the sequence containing the 1x4 lights and half tiles.
It added one single one, all the way at top of array, and I could not get past that point.
Do I need to create another sequence for that case?
Here is a pic showing my feeble attempt, hahaha.
Basically, I need to get the red box down to the green box.
And I thought I was starting to really understand this one
Maybe it would be easy at that point to make it as RC instances, but would still like to know how to accomplish it in RC.
