File info :File consists of a mesh shaped like a shield that is undergoing a softbody sim. Uses 4 individual materials.
My aim : I need to use Bump on the entire mesh to apply light surface imperfections through a Musgrave texture + Bump node
I saw various tutorials on Youtube involving bump mapping using a noise texture connected to a Bump node connected to a shader's/Principled BSDF's normal input.
Basically, these node setups contain a single shader, so there is a single noise + bump plugged into a shader's normal input.
However, in my file's material I downloaded off the Internet, there are various many shaders, connected to each other through Mix Shaders, etc
