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