I have another question.. When I'm making my animation (using the Plexus plugin) I can see that the frames don't change smoothly one into another, it has little breaks, like if my internet was slow or something.. (but it's not) Like it had problems uploading the content. I thought that it's just a render issue inside of AE, but when I exported the file with the best settings, it's still the same.
Do you have any suggestions what I could change?
Plexus evaluates strictly on a frame-by-frame basis. It doesn't do any temporal smoothing. Everything else depends on your settings for the connection ranges, falloffs and similar parameters, but without knowing them, nobody can advise. Start by extending the range thresholds and use a rounded falloff to make them fade in and out more gracefully.
