I was looking for an acceptable way to do clouds or dense smoke, and after experimenting for a while, I have developed a technique that obtains a good realistic level.
Here is the result. I used the Gimp for color correction, lens flare and a bit of glow for the sun. I hope you like it.
1- A particle system using a sphere/icosphere.
2- A material with SSS to simulate cloud light dispersion.
3- Composite Nodes to create the clouds disturb.
The details can’t be explained here, but I have made a document describing the technique implementation:
I will be very happy to know your results/ideas/critics.
1- A particle system to create the clouds.
2- A material with Subsurface Scattering to simulate clouds light dispersion.
3- A Composite Nodes setting to make the turbulence.
The details can’t be explained here due it’s extencion.
I prepared a document explaining the stuff, but the posting with the document link is waiting for the moderators permission.
