Render wireframe in RenderMan 23 for Maya
In this article, I will be explaining how to render wireframe in RenderMan 23 for Maya, for this process I will be using Maya 2019.2, but this process should work with any version and service pack that supports RenderMan 23.
RenderMan offers integrators, for this process we will be using PxrVisualizer which offers various types of styles of output, like shaded, flat and normal.
