### Shading

I kept the shading process as minimal as possible, connecting the texture maps created in Mari directly into the PxrSurface shader in RenderMan. Apart from a basic remap node used for fine-tuning the roughness response, no complex node networks were built.

This approach worked well because I had also used a PxrSurface-based setup during the texturing phase in Mari, which helped me achieve consistent results in RenderMan.  
To ensure physical accuracy, I applied correct IOR and Extinction Coefficient values for each material.

Since all maps were prepared with these values in mind, no further adjustments were needed on the RenderMan side.
