Can’t wait for the cumulonimbus preset, it was the first thing I wanted to try and make 
I struggled for a long time trying to work out how to make a very tall expanse of 3D clouds that had nice natural shapes. The screenshot I posted earlier was the closest I’ve come to the look I want to achieve.
A question about interpolating between cloud sequences - is it possible to lock the interpolate at a certain percentage, and not have it animate from A to B? For example, say I’ve got a sequence with very low extinction/high diffusion clouds, and another with more dense/heavy rain type clouds. Maybe they have different base layer heights etc etc. The kind of sky you might get after a storm say. Is it possible to do a 50/50 mix of the two?
is there a performance hit whenever you blend from one sequence to another?
