Possibly with animation nodes? I have no idea here.
To me, seems like the emitter is the object and then use a Charge with the particles having a self effect of Force.
But that doesn’t seem right. I guess my goals would be:
- Learn how to get objects to stick to an object.
- Learn how to get particles to “push” each other out of the way along said surface.
- Change particle color over age (probably).
