Color chart Shader

[Richard_Coley]

Hi,

I’d like to recreate a digital version of the xrite ‘macbeth’ color chart as accurately as possible and was wondering if anyone knows what the specular/diffuse values (including roughness) would be for the swatches? I’ve seen the in the past that shaders have been created without any specular, but I feel like this isn’t quite accurate - maybe I’m wrong though! I’ve also had a look at the some websites that measured the spectral reflectance of each swatch at different wavelengths but I have know idea how to transfer that information to a shader.

Thanks in advance.

Have you tried Dusan's Lookdev kit?
