Hi folks,

I would like to change the roughness value on different parts. As far as I understood the roughness node is connected to the scratch and fingerprints values and cannot set manually. If I unplugg the roughness I can set my desired value but get lost of the beautyfull details like scratches, dirts ect. Is there an easy way to set the roughness without losing the details? Maybe it can be solved with an Mix Node. Can someone help how to solve it?

Thx in advance and have a great day, cheerz gt

Mecabricks sets the roughness of a part by processing the normals, not by using the "roughness" input. It is closer to what happens in real life and it works nicely for close up shots. So you have 2 options. You can change the strength of the node group located in mb_normals > mb_roughness
Or if you really want to tweak the roughness input, use a math node (or mixRG😎 set to ADD for the roughness output of mb_customize.

Hi scrubs,

thx for the tip, tweaking the mb_roughness makes what i was looking for. Yes, The original roughness output is very close to real life, sometimes just for aesthecial purpose you want to reduce the glossyness to look smoother for better reading the image especially when a lot of lights are lighten the scene.

Thx and have a great day, cheerz gt
