I was trying to do the same thing but it wasn’t work?
Can anyone help em to find the solution
(Render is Cycle)
It is working, but the value you put there is too big. Bevel node is to make thin bevels and not so thick ones. 11 centimeters is too much. Try a 0.02 value and you will see the effect.
Also, the effect is better viewed in areas where you don’t have sharp shadows.
