Cloud

Simulates clouds.

You should only map the Cloud texture to a sphere. You can combine several spheres to create complex cloud arrangements. If you map the Cloud texture to any other type of surface, the results may be unpredictable.

The area surrounding the cloud is always transparent, regardless of the map type.

Find this texture in the Create bar. To apply this texture as a texture map, see Map a 2D or 3D texture.

Color1, Color2

The two colors blended together to form the cloud. To select different colors, click the color bars to open the Color Chooser.

Contrast

The contrast between Color1 and Color2. For example, if the Contrast value is -1, Color1 and Color2 are reversed. The range is from - infinity (the two colors are averaged over the entire texture) to + infinity. The default is 0.5.

Amplitude

Controls the strength of the fractal noise used to generate the Cloud texture. The valid range is 0 (no noise) to + infinity (strong noise). The default is 1.

Depth

Controls the granularity of the texture. Values represent the minimum and maximum number of iterations used to calculate the texture pattern. The range is 0 to + infinity. The defaults are 0 and 8.

Ripples

Determines the texture’s waviness in the X, Y, and Z directions. The values represent the frequency scale of the fractal used to generate the texture. The range is from 0 to + infinity on X, Y and Z. The default is 1.

Soft Edges

Simulates natural looking clouds. Gradually increases the transparency of the texture as the surface it is mapped to turns away from the camera. If Soft Edges is off, the texture is entirely opaque, and looks similar to the Fractal texture. Soft Edges is on by default.

Edge Thresh, Center Thresh

If Center Thresh is low and Edge Thresh is high, the texture resembles a dense cotton-ball. If Center Thresh is high and Edge Thresh is low, the texture resembles a wispy cloud. The range is from - infinity to + infinity. The default is 0 for Center Thresh and 1 for Edge Thresh.

Transp Range

The range over which the texture becomes transparent. The value controls the sharpness/softness of the cloud’s edges. The valid range is 0 to infinity. The slider range is 0 (sharp edges) to 1 (very soft edges). The default is 0.5.

Ratio

Controls the frequency of the fractal noise used to generate the Cloud texture. The range is 0 (low frequency) to + infinity (high frequency). The default is 0.707.
