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.
