I am working on a project right now again in which I am having a pretty futuristic looking submarine underwater, working with jet propulsion. I want the blast pipes to spit out blue light, which is no problem, but I will also need many many different sized crowded bubbles behind them.
Just to give you guys an idea what kind of look I am after:
The end result is going to be a still image, so I have not planned to animate anything.
Thanks for reading and for any ideas! :)
