Increadible pack, had to buy it from sale and dont regret. Just simply amazing. As small problem, havent managed to create POM materials yet since the height map is combined with other textures. Is there way to convert texture object to use only the alpha channel? Or should I make duplicate of the texture and disable other except the height map? I am bit rookie with the materials still so any advices are always welcome. 
Edit: Or nevermind, I duplicated it and set RGBCurve and saturation to zero. Working superb now.
