It is possible! You got lucky because I still have time to put this exactly picture in the “How-to” video series Im preparing, so you will learn step-by-step how to do it. It will be based the new material I released in the version 1.1 for the Cumulus clouds, but the height will be using the height for the Cumulonimbus. We can mask some space in the layer texture section to have the areas we want more empty while surrounded by those majestic mushroom like shapes. About the colors, we need to tune the density + extinction color + ambient color to have those bluish shades. The interesting in this photo, is because was it was took in a very high altitude (by the camera angle and cloud formations, around 7,000 meters sometime near 2pm during Summer nearest to equator line), the sunlight is basically white and this one gives the most beatifull scattering effects for this particularly picture. There will be a second cloud layer for that Cirrus cloud which looks like a veil at the most high altitude (8,000 meters approx). Also, the turbulence which causes the crispy effect have to be zero to preserve the cauliflower shapes at the top of the clouds.
You can place 0 at the wind strength bp in each clouds layer to have it static and you can fly between the clouds starting at the camera position going down, making sure the Raymarch steps is minimum 360 and still have more than enough FPS for cinematic capture. The better sunlight for performance is the static or stationary ones if you want seeing the landscape bellow the clouds at some point during the cinematic.
The videos are under production and I will release 5 at once, being the next ones released in 3 days interval. The amount is not fixed, because we are still waiting for user sugestions or doubts to increase the video count, but they will be at least 20 vides from 10 to 20min.
