Wall of Clouds
January 7, 2007
First, credit where credit is due. This tutorial is not original! It is a reworking and enhancement of a tutorial found here. The original is in German, so I thought I'd rework it for those who find the Bablefish translation hard to follow.
There are three steps to making a 'Wall of Clouds'. Get some clouds, look at the clouds and get your camera close to the clouds.

Step 1) Setting our random seeds to 1, we start with this .tgd file. It adds an Altocumulus 3D layer and a Density Fractal shader to the layer.

Step 2) Next, we rotate our camera and move it to point to a dense section of clouds. Then we adjust the various density values to enhance our clouds. The resulting .tgd file can be found here.

Step 3) There are two ways to get close to your clouds: move the camera or move the clouds. We'll move the clouds by changing the 'Cloud altitude in the Altocumulus layer's Main panel. The resulting .tgd file can be found here.
Note the changes in the Density fractal window. In particular, we've reduced the Contrast and upped the Roughness. |

Last, to add a little spice to our picture, we'll do a 'Generate now' in the Heightfield generate, then change the Position in the Location panel for the Heightfield shader. This moves our mountains under the clouds. You can look at the final .tgd file here. |
