So I have this particle storm but cent seem to figure out what settings relate to the tail being so broken and "non wispy". Right now it looks more like Mac and Cheese. The idea is to have the tail end quickly but look like vapor as it ends. Thanks for the help too, it is much appreciated.
What exactly does vapor look like to you? The broken look is probably because you have the particles spreading out over time or have their size decreasing over time or both. If you want them to get bigger and fade out, animate their size up over time and animate the opacity down to 0 over time. That way they will grow and fade out. Should fill in the gaps and give you the transparent look you are going after. If you have a pic of the vapor look you are going for, post it and I will see if I can be of any more help.
