In order to support a dynamic amount of particles, particles are marked as being valid or invalid. This is achieved by two means: The valid particle range indicates the range within which particles may be valid. Outside that range all particles are defined as being invalid. Within that range valid particles are marked with the flag *PxParticleFlag::eVALID*.
