Rusty flasher needs help

Hi everyone,
It’s been a long time since I’ve done any flash and now I have an opportunity to put my rust to good use :slight_smile:
I’ve been trying to figure out how to do a contrail effect but have been unsuccessful.
This is what I have:
I have these “dots” that are moving around a motion guide in a sort of “orbit”, moving faster and faster. What I want to accomplish is turn these dots into contrails and eventually into something else.
My question: how do i make these dots “morph” into fast moving smoke trails around an object?
Thanks! :tie:
