By that I mean things with a specific shader are rendering black, though the shader will render if I disconnect everything except ye olde diffuse, glossy, and mix shaders
For brevity, here's the blend.
Today, I rendered again just to reaffirm the problem, but the model did render for some reason. At this point the shader was the exact one in the blend file I linked. Again, still an exceedingly simple shader at this point.
But when I attempt to plug something into the material output's displacement (I wanted to try the same texture data used in the mix shader's fac input, if it matters), the model renders black again.
- The shader's preview in the outliner panel shows up properly
