Hi I’m trying to make a interactive snow ball like this.
I’v tried to set some velocity on the particles when the sphere is moved, but I can’t get the effect of randomly flying around snowflake dragged by the flow.
I think if I simulate a fluid with some flow in it and use the forces in the points where my particles are it will make more realistic effect.
I really have stuck, I’ll be very grateful if someone can help me and point me in right direction
