Im trying to create an underwater scene which the player can move around on the seabed, to make it more realistic i want to have 'dust clouds' appear from the seabed when the player is running around the seabed. I have tried top recreate this using unity's particle system with little success, it seems to get an actual 'cloud' effect i would need thousands of particles which would slow down the system dramatically. Is there any tips on trying to acheive this effect? Basically all i want is a puff of dust to rise from the seabed! Appreciate your time!
