Iray metalness / roughness Cheat Sheet

Just a quick "Cheat Sheet" for the metal shader included, which I rendered in the new DAZ Studio beta.

The scene in the chart is a simple "studio HDRI" I got from 3D World Mag a couple years ago plugged into the environment, with a sphere primitive. The diffuse color in all is 192 R 192 G 192 B grey.

The top chart is simply metalness versus roughness. The top row is 0% roughness, with each row down adding 20% down to the bottom row as 100% roughness. The left hand column is 0% metalness, with each column adding 20% metalness to the far right being 100% metalness. These figures are also applied to the Glossy Reflectivity and roughness, as well, in each image - 100% Metalness and 40% roughness also has 100% Glossy Reflectivity and 40% Glossy Roughness, as well.

The bottom chart simply compares Metalness to Glossy Reflectivity, with roughness set to 0% for both. Top left is 0% for both, top right is 0% Glossy Refl / 100% metalness, bottom left is 100% Glossy Refl / 0% metalness, and bottom right is 100% both. This means that "glossy reflectivity" acts more as a specular, rather than any form of true reflectivity.

This might be a big help, eh?

    There's so much more that could be done using the various iray settings, too... Cheat sheets on refraction, displacement settings, etc etc...
