I'm trying to add small scale displacement to an object that i've imported. I don't want it applied to the whole object only part of it. So i've gone into the objects network and found the default shader for the part of the object that I want displaced and added a power fractal shader between the default shader and the multishader. The problem I get is that once I add the power fractal the part of the object thats controlled by that default shader just balloons up and grows instead of just displacing small parts of it. I thought maybe I should be plugging the power factal into the default shaders displacement function field but that didn't seem to do anything.
