I'm using the Stretched Stratus cloud with:
Altitude 0km.
Height 10km.
Cover 68%.
Density 98%.
Opacity 81%
Sharpness 8%.
Feathers 5%.
Detail amount 5%.
Altitude variations 0%.
Ambient lighting 60%.
Shadow density 60%.

For the mat's Cloud layer detail, I'm using:
Scaling 25%.
Roughness 59%.
Variations 45%.
Uniformity 58%.

The Custom cloud layer profile is the image above.  The left side is the bottom (ground shockwave).  The right side is the top of the mushroom.  The top is the profile shape that gets spun around the Z axis.  Somewhere around the middle is the Z axis (0.00 level).  The top I have go negative so that there is some air pressure at the top going on.  Just a trial mockup.

I'm using Vue Infinite 8.
