PxrDisney and RenderMan Preview Rendering
The PxrDisney shader is RenderMan’s default for a reason- it’s fast, easy, and extremely versatile.
Check out the awesome documentation here for more examples: http://renderman.pixar.com/resources/current/RenderMan/PxrDisney.html
The PxrDisney shader is the ubershader of RenderMan. It’s great for basic solid objects like simple metals and plastics.
From the documentation linked to above:
The PxrDisney shader is a “catch-all” shader, designed to be flexible and dynamic in a production shading pipeline. The shader is based on the Disney “principled” BRDF by Brent Burley; it is “principled” rather than strictly physical. The principles that Disney followed when developing this model were:
- Intuitive rather than physical.
- As few parameters as possible.
- Parameters are zero to one over their plausible range.
- Parameters are allowed to be pushed beyond their plausible range where it makes sense.
- All combinations of parameters should be as robust and plausible as possible.
