Yeah, I am real happy with how the missiles worked out. I had to cut down a bit one the amount of lights I was spawning, from the beginning every blob of smoke was a light as well, but I had some weird crashes (once) from it, didn't wanna risk it.
Yea, I think having too many lights in Bevy has issues. I had 4 point lights/room in “Station Chore” and beyond that it would cause larger lags spikes. Probably deferred rendering addresses this issue, but I have yet to try it out.
