light fog

[sparkChan]

hi, I don't know how to create a light fog effect in houdini.

but if I use Atmosphere node to do it, it will take more time to render.

In Maya, it just take one more seconds.

thanks.

there have two ways:you can just use the Atmosphere node with the shop of lit fog. Actually,the theory of light fog is just the light through a big fog,so the other way is you can make a noise in COP,and put it into the projection map of your light,it can be produce the light map.Of course ,the light must point the fog which you make .Pay attention the attenuation if you make the light fog under water.....
