point lvl 1
direction lvl 2
lacing longest
node from data-shapes
but not sure why it doesn’t work
btw it works if i set only 1 direction with no lvls or lacing
edit: it doenst give null if only direction is set to lvl 1 but it gives random structure
I don’t think it’s random. The node seems to be setup specifically for multiple points and a single direction. This is why a single direction works with no list levels or lacing. Adding more directions is the only change you have in input structure - which is also why your change to Direction_ @L1 executes.
It would be helpful to see the output from Direction_ @L1. You can even “rebuild” the ray bounce vectors to confirm you’re getting the proper output.
