@methusalah said: The problem is not the number of particles emitted but the place where they are emitted. increasing the number of particles will give me more particles on the same emission point.I will try some extension of the ParticleEmitter, to make them spawned at the good location and time regarding the position and emission time of the last update, by interpolating.
But if you have more particles per second, you will have more emission tick…so less intervall between them…less gap…
