sCloud texture

sCloud Texture Parameters

Color1, Color2

The two colors that are blended together to form the cloud.

Contrast

The contrast between Color1 and Color2. For example, if the Contrast value is -1, Color1 and Color2 are reversed. The slider range is 0 (the two colors are averaged over the entire texture) to 1. The default value is 0.5.

Edge Rolloff Parameters

The Edge Rolloff Parameters determine how the texture’s transparency changes as the surface it is mapped to turns away from the camera.

Soft_edges

Gradually increases the transparency of the texture as the surface it is mapped to turns away from the camera. This simulates natural looking clouds. If Soft_edges is OFF, the texture is entirely opaque, and appears similar to the sFractal texture. The default setting is ON.

Transp_range

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

Center_thresh, Edge_thresh

Determines how diffuse or concentrated the edge rolloff is. If the Center_thresh value is low and the Edge_thresh value is high, the texture resembles a dense cotton-ball. If the Center_thresh value is high and the Edge_thresh value is low, the texture resembles a wispy cloud. The slider range is -1 to 0 for Center_thresh and 1 to 2 for Edge_thresh. The default value is 0 for Center_thresh and 1 for Edge_thresh.

Noise Parameters

The Noise Parameters control the fractal noise used to generate the sCloud texture.

Amplitude

Controls the strength of the fractal noise used to generate the sCloud texture. The valid/slider range is 0 (no noise) to 1 (strong noise). The default value is 1.

Ratio

Controls the frequency of the fractal noise used to generate the sCloud texture. The slider range is 0 (low frequency) to 1 (high frequency). The default value is 0.707.
