I am making a whale breach and as all the GPU particles burst out of the water (with the whale) I also want to “froth” the surface of the water. I have thought of two ways of doing this.
one, I could make a decal with a frothy material that scales and fades way. Or two, I could add it to a particle that sits just above the surface and scales and fades away.
How would you approach it. As a decal or a Particle emitter?
