I am preparing for a non photo-realistic 2D animation that shows a substance moving through a hose. I want particles to go the whole way through the (transparent) hose which also is curved in different directions. When they hit the inner wall of that hose they should bounce back in the middle, following the stream direction until they come out at the end of the hose and die.
Is this possible with blender’s current particle system? Though I am experienced with modeling and texturing I am a noob to particle animation. Maybe there is a good tutorial around that shows how to make particles follow a path and interact with barriers and obstacles?
