I would like to know in fact that's how we should proceed to have this same shader, especially what is circled in red, because the rest I can do :)
I'm sorry I haven't view the example of shaderforge in marmoset....ou can deleted this post....;)
What's your problem ? If you want shader like Skyshop or marmoset ...
I made what your want ... I made Marmoset Tool-bag 2 Shaders .
Just pm me your mail , I will send it .
