I’m on a rather unusual task at the moment:
I would like to animate the process of high pressure washing with a waterstream.
I have already modelled a high pressure lance with a nice smoke stream coming out of it (looks like water in combination with a wind field).
But I’m still not sure how to animate some kind of dirt (e.g. small plants and so on) beeing washed away, only leaving a clean surface.
It might be only by changing the texture in the affected area or - even better - actually throwing particles away from the spot of impact.
Have I expressed myself clearly?
Do you have suggestions?
