Hi Jean-Francois, Particle systems on moving models need to keep the emitters attached to subgraph below any transforms that are moving/placing them and the ParticleSystem itself attach to the root of the scene graph to make sure that it's placed correctly. See the osgparticleeffects example to see how it handles moving models.
