need a sugestion

[ncc1701d]

hi,
Volcano eruption gasses when erupting have the tendency to dissipate as they get higher in sky. Anyone have good suggestions on how to do? I have my gain and bias get less over time which is good. I am hoping to get it more fussy and less detailed overtime and even more transparent over time. suggestions anyone?
thanks

You can also try to lower density over the particle age and make particles to grow as well.

Maybe you can try decreasing the "Noise Levels" over time as well to make the gasses less detailed?
