   need a simple foam shader.
  Hey !, I work on a project that needs foam after a boat.The current implementation is with a particlesystem, and dont look very well imo. Do anyone have some ideas of a easy solution (i have very limited time).I tought of a shader , maybe a shader ?, but how do i write sucha shader easiest way ?, ... is there anyway to get the particlesystem nicer, any trix?well ty for any fast advices   
  Im not sure exactly how to write a foam shader, but the way I would make it look nice is apply a normal mapped fowm texture and add in some type of subsurface scatteringno idea how to actually implement that but you would have nice looking foam that way (i think)
