Thanks Slin, following your advice I downloaded that huge collection. Now I have the same problem as everybody else (more or less). Running the shader from the .exe you provide it works - looks great! If I open the source and run that in WED it doesn't, I don't build the level at all (use the existing wmb) and still nothing. Same thing if I add it to my own project.
Any ideas on this, it has me stumped
Thanks,
James
