Firstly, I was trying to filter a list of points against some criteria - like I’ve done many times - but the nodes are creating tiers when none were expected. Each has the same number of enteries and I couldn’t see any null operations. Secondly, when trying on my own to clear the empty list, I couldn’t remove it or flatten it with the 5 or so different nodes I tried and any help clearing the empty list at the beginning would be appricated. Thanks.
The empty list is just the output of the ‘in’ port on the node, in other words: your entire list for the mask is false. Connect a watch node to the ‘out’ port and you’ll see the empty list is not there.
Interesting. Interesting. Thought I tried that but will try again.
