By 'spraying' you mean increasing how quickly LMB fires off LiDAR points?
Either way, it is certainly possible. The system I'm using can support millions of points without much FPS loss; I'm just keeping the amount low because it 'makes more sense' versus the setting of 1990s for it to be capped to (presently) 65535 points of data. (ed: That said, I am actively listening to player feedback and it's not something I would mind adjusting if there's calls for it)
I am considering on the backburner things like discoverable upgrades that expand the amount you can have scanned, scan speed, scan fade distance, scan density, and battery maximums and charge speed. Would those be things you'd be interested in exploring the exclusion zone to find?
