Is this supposed behaviour? Wouldn't it make more sense to always draw at least maxParticles amount of particles?
Reproduce by watching any big teams game with low particle limit(10'000) and see how suddenly all particles disappear after some time. Or just spawn some particles and vary particle limit to see them disappear.
For me not seeing particles is a big handicap because it makes missiles nearly invisible.
[Spoiler]Imo particles should be handled by the engine, but I don't know much about how spring works.
I'm not sure where this belongs as lups isn't zk-specific nor is it engine-related.
Feel free to "move" this to the appropriate bugtracker.
