Title: Edge Color - what is is and why is it greyed out?
Post by: dacian on 2021-04-06, 16:11:22

I'm looking at the new Physical material and the greyed out Edge Color in the Base Layer.
How do I use that?

It only applies for Metal materials, and is greyed out for non-metals.

PS - the presets give the physically correct Edge Color for various metals, and we are working on a map that will let you enter the parameters for metals available on tables online, and that map will correctly calculate the Base and Edge color for you, if all goes as planned - so even then you won't need to manually adjust the Edge color :)

Thanks!
I’m actually looking to make an iridescent material, something with many colorful reflections. Not necessarily physically correct. Any tips on that?
It would be helpful to add some hints in the materials to let users know why things are greyed out. I remember at one point in one of the volumetric parameters it was written there it only works when refraction is on.

Hello,

do you perhaps mean something like this? ;)

Thanks,
