I need an advice to achieve a LERP inside a decal material.
What I’m looking for, is to make a linear interpolation between the left decal to the riht one (my goal is to control the thickness of a vynil stickers). The purpose is to LERP between underlying surface NM and a flatten NM.
When nothing is connected in the input normal, I get the normal map from the underlying material, which is what I’m looking for. But I would use a LERP in a single material, and I need a value to connect in the A LERP input to keep this underlying normal map… In terms of theory, I would use the value wich is used in the shader when nothing is connected but I don’t know this value.
Would anyone have an idea to achieve this?
