I found Material cant reach paramteres in material function instance when i attached to material.  
For example  
GravelMF(collect all parameters and textures for single layer)  
=\>GravelMF\_inst(have all changeable parameters like in any instance)  
=\>Put material function in Landscape material.  
=\>Trying to change some parameters in material function does not any affect on landscape material
