Hi Christophe, Could you please modifiy one of the particle examples to reproduce the problem, then others will be able to see first hand the problem you are trying to address. As a general note, lighting particles in a conventional way is something I'd see as somewhat dubious. The particles aren't real geometry, rather image based rendering is used.
