Hi All. I checked a shader network of aged metal shader in the material paltte. I wonder what this parameter node called “pattern_Export” does. It is connected to the plug called “dispAmount”. So I guess this one controls the amount of displacement value. Is this one of the global parameter that mantra uses at rendering? I don't understand why you have to make this connection other than output1. It more makes sense to me if the output1 has this “dispAmount” plug. Thanks in advance.
it exports the displacement texture, in this case some noise pattern to a variable called “pattern” for the later use in surface shader (notice dimport_pattern node in metalSurface)
