Description:

PBRX is a physically based, all-in-one shader designed to serve as an alternative to the already existing Principled shader. PBRX, though a decent improvement over the Principled shader, does have some drawbacks. So to be a little more honest, I've decided to create a pros and cons list to give a better understanding of the shortcomings as well as the advantages of PBRX when compared to the Principled shader. I do also release updates for PBRX from time to time so check in to make sure you've got the latest version.

Pros

  • Diffuse Roughness Control
  • Pseudo Spectral Dispersion in Transparent Materials
  • Improved Clearcoat
  • Built-In Bump
  • More accurate Subsurface Scattering Controls
  • Improved Energy Conservation on Smooth Materials
  • 2D Transparent Materials

Cons

  • Inaccurate representation of Fresnel falloff at roughness values greater than 0
  • Lack of Multi-Scatter GGX support
  • Lack of Oren-Nayar reflectance support while using Subsurface Scattering
  • Produces unwanted noise in Eevee when roughness is greater than 0
  • Clearcoat roughness not supported on materials with anisotropic roughness
  • No sheen support

    Needs a side by side comparison of what makes it better then the Principled shader.
