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 w/ PBR Ior Calcuations 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
