Create cloud effects using solid textures

Rendering > How do I > Apply solid textures >

To create a cloud using the sCloud texture, create a shader and set the shader parameters as follows:

Set Shading Model to LAMBERT
Set Color to white (or grey for smoke)
Set the Refractive Index value to 1
Map Transparency with an sCloud texture.

Transparency is a 3-channel (RGB) mapping. As a result, the sCloud texture requires more settings to work properly as a transparency map. Set the sCloud parameters as follows:

Set Invert ON
Set Color1 and Color2 to white
Adjust the Transp_range value to make the cloud more dense.

Apply the shader to a sphere.
