FogPaint

Concept: This texture looks at the colors already on the fog object and everywhere the red color gun is turned up high, the fog will look thick - as the red color gun gets turned down, the fog gets thinner.

Key Points: You could apply a texture or a brush of a particular shape, and "paint" the fog to be thicker where you want it to be. The texture must be used on a fog object with an initial fog length setting (.1 works well but, of course, the best value depends upon what you are trying to accomplish). The noise that is added to the texture can be sized and positioned by editing the texture's axis and color can be added to the object with attributes, brushes, or textures - or you can use the color values in this texture itself.
