This doesn’t appear to be common knowledge… I got this from a thread from 2014 but it hold true.
Take your instance count and subtract 1, it’s an array so since it’s base 0 it needs that applied to work, but I did it and it works perfectly.
I build my level using procedurally generated HISMs, I want to trace around them to place more actors. I don’t know how many things will spawn so I have to trace every HISM Component. If there is no valid instance it jumps to the worlds 0,0,0 for the trace and spawns the actors there; which isn’t what I want.
I tried is valid node and making sure the hism has an instance count of at least 1 but it still won’t work.
