Extinction coefficient

Michael 2 years ago updated by Vitaly Ovchinnikov 2 years ago 2

It appears that Owlet has support for extinction coefficient (k value) when defining metals, but it appears that Boxshot only has support for the refractive index value (n value) — unless I am missing something? 

I am trying to recreate glossy metal surfaces using known values, such as from: https://refractiveindex.info/?shelf=3d&book=metals&page=copper


Yes, Boxshot has simpler materials. Consider turning fresnel reflection off and using Reflection Level slider and Reflection Tint control to create metallic materials.
