Hi,lets start with nuts and bolts.the nuts and bolts i have modeled from a tutorial,for practicing.all selfmade procedual textures.


Study of Iron and Iron-Rust.Rendered with a Wolf and Born and Gulbrandsen equation for nk metal values into the principled shader.
For the Fe3o2 Rust i added a nk equation that handles dielectric attenuation,that gives Fe3o2 this typicall red-brownish color.


For this i changed the material to one Fe302 nk input and used a heightmap to drive the rust amount from the shader.
