Mix Shader

Multiexcerpt
MultiExcerptNamemix_shader

mix_shader is used to layer two different standard_surface shaders. We will use

...

one standard_surface shader for the top green paint layer (green) and

...

another standard_surface shader to represent the exposed metallic surface underneath.

  • Create a 

...

  • mix_shader and assign it to the object.
  • Create a 

...

  • standard_surface shader and rename

...

  • it 'Green Paint'.

...

  • Create another

...

  • standard_surface shader and rename it 'Metal'
  • Connect

Note
You could also use the Mix or Layer shader instead of Mayas Layer
  • the Green Paint to Layer1 of the mix_shader and the Metal material to Layer2 of the mix_shader.

Curvature Shader

Multiexcerpt

  • Connect a

...

  • noise shader to

...

  • the radius

...

  • of a curvature shader (bias and multiply will work too). Experiment with different noise settings to get the look that you want. Don't forget that you can connect a 

...

  • color_correct shader to

...

  • the noise shader to further refine the appearance of the 'worn' look.
  • Connect the 

...

  • curvature shader to the 

...

  • transparency attribute of the layered shader. This will control the blending between the two

...

  • standard_surface shaders.
