Benefit of Principled BSDF over Glass BSDF

[Ailurus_of_the_Seas]

Hi, just wondering if there’s a specific benefit to using the Pricipled BSDF node over the Glass BSDF node when creating a glass shader?
Thanks!

To the best of my knowledge, there’s one main reason: Changing the Color of the Glass BSDF will also tint the color of the reflections — which is not physically accurate.

Using the Principled BSDF (with the Transmission weight set to 1) and changing the Base Color will correctly change the color of the glass, while leaving the reflection tint unchanged – so you essentially get the best of both worlds.

Principal BDSF gives you PBR results. In other words a more realistic glass material. Glass BDSF is quicker to calculate, but not as realistic.
