You are so kind for keeping up with me, thank you !!
I replicated almost all the BPs you showed me.
Except
1- can’t create the combined “Target | Sequence Number” node - levelBP
2- when I call out the functions they appear as blue and not green like yours - levelBP
3- can’t connect the Next Light node to the Target slot in “Light Sequence” - ObjectBP
attached my current BPs
much love!
