I search for some physical background of steel material.
I know that some light is reflected and some light is “absorbed”.
but how many of them for typical machined steel?
Here is a rendering image i found:
This steel look realistic - but i could not reproduce that.
and here is a real image for reference:
Notice that here are also some strong light reflections on metal looking nearly white
My pure glossy steel look more like a rough mirror.
I set glossy color to 0,456 for RGB (0,7^2,2) and it reflect too many light back (so i see reflecting spots).
It look not so natural… i think i need some mixing with diffuse to fix that.
My material look also a bit too dark
