I ve recently got the nemeth ec135 and downloaded the gfees texture that can be found on this sites downloads. In dx 10 this makes for a seriously reflective & shiny and jazzy looking heli but having had a look at the dds files the one difference seemed to be having a fresnell dds file included (though this looks to be a greyscale from white to black only 4 pixels wide)
I was expecting the spec map to be really extreme but it isnt - just a green shade
can anyone explain what the fresnell shader does for fsx? and whether it would be applicable to all aircraft ie if you put a fresnell.dds into another aircrafts texture folder could you have a similar increase in reflectivity?
