cloud experiment

I have been experimenting with basic clouds in my cityscape today. I followed a tutorial on YouTube on how to do this you can watch the video for your self here https://youtu.be/g8A0Etf-ekY. While it was easy to do and while at some angles it dose look nice overall it dose seem to be a bit much where the clouds do not look much like clouds and were also lagging unreal engine 4 making it hard to work on.

This is my blueprint of the cloud material.
