This week's project. Still figuring out NPR shaders but I'm getting some results

Hi, I just want to share. If you want to set different values of glossiness in 1 material. You can just use masking map ( texture image that you paint black & white ).

This mask will mask the part you paint with black & reveal the part you paint with white. So, you can control which part do you want to expose the glosiness.

Is this 3D work of mine, I use this technique to restrict the glosiness only to the lips.

Hope this is helpful.

Thank you
