   glFogCoordfEXT and z-distance fog
  Is it possible to use the vertex fog and the regular z-distance fog?  If so, can they be different colors?  I haven''t had a chance to experiment with this yet.  I noticed that a NeHe tutorial I skimmed used the usual glFog commands to set up the vertex fog color, etc, so that got me thinking about it.  I may be missing something obvious.  Thanks for the help. 
  yes, you can use both at the same time. and they will have the same colour. ;  666_1337 could you possibly give more details, I posted the same question a while ago and got no replies. Do I have to do 2 passes? Please help!!
