I thought it was something like you show in the below post. So as long as it’s within Va, Raytraced probably can’t read the material definition so it goes with “By Layer” which is how the rest of the window is set up for material definition. But all the other render modes can read it correctly, but in the instance of Raytracing this is another case of incompatibility between Rhinio and VisualArq.
Sheesh. Sacrifice parametric ediitabilty for a render, or manage multiple versions of the same project for every render.
