You can use normal map, normal map is like pixel rotation and each color chanell represent each axis X = Red Y = Green Z = Blue, opposite sites will be black because it gonna be negative numbers and GPU put black color on negative numbers. You can use that map to switch between different series of material nodes (2 materials in one) depending on blue value (Z axis). I’m not experienced with material editor, but you can use “PixelNormalWS” node, problem is it is effected by object rotation, there probably ways to fix it, so treat my answer as starting point ;]

Hi , thanks for your answer, but can you post some simple example because I really do not understand what you mean. Thanks

I found “SM_GlassTechPanel” from GDC2014 (in marketplace) which is closer to the real glass edge
