Hi, I''ve been reading a lot of info about volumetric fog and how to calculate it. I understand how it works with just verex fogging but there is VERY limited info about using fogmaps. As i understand it they create a grid of points accross a surface, but I still can''t seem to get my head around how this is implimented... Any help would be appreciated, thanks

Thanks for the reply, but do you know any sites that have information about using fogmaps? I''ve tried searching the net but the closest i''ve found is subdividing the geometry and using the vertices?
