Finally dirt & grime for the CAD folks!

Okay, the nodal material system is seriously awesome...
Endless possibilities to add subtle (and less subtle) shading variations to CAD geometry. Nodal materials and procedural textures are a killer combo!
The Material Graph is actually a lot of fun to use.

Just scratching the surface. Pun intended.

Most complex node graph i have seen thus far Dries
Great looking result too

Sweet!

Thanks, guys!
This shot shows the materials a little better.

OK, so here's a final shot with just HDRI. Thought the physical light artifacts were a bit distracting.

Nice. Although some funny stuff are happening at some of the edges, it looks quite cool. Good job!

Can I ask what settings you used for the color randomize node? Just curios to see how well the node works. I primarily added it to support random color variation on curves (where it can add a random color change on a per curve basis), but always nice to see it used for other things .

Wonderful Dries, I knew the Material editor would be right down your alley...I know what question I'd like to ask though

Søren,

I pretty much used the standard settings. I attached a rendering where I disabled the curvature opacity texture for the Plastic material (see Material Graph above).
The result is a bunch of a sharp edged facets. Not very elegant as a standalone texture, but it works quite well to introduce some subtle tonal/... variation in the 'rust' patches.
Maybe the color randomize node can be improved to have blurred facets?

Ahh I see. The facets are the mesh triangles. I think what you need is procedural like camouflage but with more control over the patch size, shape and color, correct? That is much easier to blur as well. I will add this to the todo-list for 6.1.

I expect to change the color randomize to only work with curves and object ids as the seed. Just a heads up .

That sounds like it should do the trick.
Didn't realize the Color Randomize node was intended for curves. Learning as I go.
