Hi !!!!

>From what I understood is that you wanted to set the fog parameters
at run-time. You could read in fog-parameters at run-time and
most importantly apply the parameters during the Draw Process.

You need to assign the parameters to the fog and the apply the fog
: pfApplyFog(pfFog *). in your draw process.

Hope this helps
