Do you know a way to change some attributes of particles, when they enter a specific area (e.g. change color/material, make them slower)?!
I also want the particles that enter a specific area to stay inside it (e.g. don't fall through it's bottom face).
I am trying to let the particles fill out a specific mesh but don't know where to start.
The "0" and "1" are my particles (always facing the camera). I want them to get slower and change their material inside the weird shaped Mesh (and the object should be invisible in the final render).
For now I just gave it a collision, I don't know where to start wwith this task. Thought about adding forces but ... meh...
I want to change the color/material within Cycles renderer in the end. But more important are alterations to the particle speed, so that you can guess the shape, if there are "enough particles inside the invisible object".
