I use planes or irregular surfaces, one or many, can be horizontal, inclined or vertical, depend of the needs. The texture is used as transparency map. The ambient color is white or can have some blue, the specular color is black and the diffuse you can experiment different colours from black to white. You can use the planes with the same texture, other texture or none. The textures that are good for the transparency are variants of Perlin noise (3d turbulence noise). In my Poser gallery are some pictures with fog.
