I made these two spheres and the lines coming out of them are cones with this material
what I’m trying to do is to imitate two positively charged particles so as they get closer I want the following to happen to the field
I tried using particles for the field before but I had a problem with moving the sphere and rotating it because one the particle is emitted it wouldn’t follow the sphere so using cones fixed this problem but now I have no idea how to do the field as the spheres get closer to each other. any suggestions would be much appreciated.
