Description of How the Clouds were made

This is all way over my head. I thought it would be kind of funny to put up. This is Ben’s description of how he made the clouds in CG.

1. Sculpt the basic cloud shape
2. Apply a particle system with 10000 particles, turn off Gravity and Normal Emission, change start and end to frame 1
3. Create a new “Clouds” Texture (Depth 3, Noise: Hard, Size varies with size of the mesh, I used 4.0)
4. Use the texture in a Texture Force Field
5. Animate the particle system. It should blow apart completely within about 5 frames. Usually frame 2 is pretty good. You want to keep the shape of your sculpt, while letting the edges get blown out a little.
6. Export as XYZ, re-import as XYZ to “freeze” the particle vertexes on the desired frame

I did that about 12 times, building up a library of individual clouds. Then I assembled them into a cloudscape.

Volume material settings: Density scale: 0.5, Scattering: 3.2, Emission: 0.1 (bluish). Point Density texture settings: mostly default, but remember to set Coordinates to Global. Turbulence: Voroni F2-F1, Depth: 3.

Lighting: One reddish sun lamp (brightness 3.3) and one bluish hemi lamp (brightness 2.0)

Post processing: none — I just added a background (sky) image
