How Does It Work?
The Density parameter sets how dense the cloud is, or how many puffs there are in the cloud. The number of puffs changes abruptly as Density increases.
The Puff_Size parameter sets the size of the puffs in the cloud. A Puff_Size of 0% will completely eliminate the puff, leaving only the Background. This is a useful control for shaping a cloud.
Hints!
Hooking Puff_Size to a percent version of an Image will make a cloud that has the shape of the percent
image. Images without any sharp edges in them work best. Using animated image sequences to control Puff_Size works well, especially if the clouds are translated through at the same time. This can give the
effect of shaped clouds moving and churning in the air.
The bump version of CLOUDS with a negative Bump Scale makes a good choppy water surface.
