Luc Scholtès posted a new comment: OK, many thanks guys. I see now more clearly how to use groupmask. I am still not sure this would be the best way to deal with my problem since the particles that I want to be invisible from the other "visible particles" should also be invisible from each others (I don't want them to interact with anything). Using groupmask, I would thus have to define a different bitmask for each of them, making sure they cannot interact one with each other... I am not sure this would be practical since I should then define the bitmask equal to 2^i for each of the i-th invisible particle and thus would probably be limited in the number of particles I can actually set as invisible... I hope this was clear enough...
