I feel like "Here's list of points I'd like Niagara to use as particle positions" is not a particularly weird thing to ask, but I found nothing about it that didn't immediately get deep into the experimental API weeds (and already broken NOW), or extremely abstracted concepts. Not once did I find someone saying "yeah you can just bung an array param in there and link it up to particle index" so either I'm super dumb for not immediately knowing that or this is a gap in the cloud brain
