Description:
Update - 06-05-2018
The Glass+ Material now comes with dispersion, connect the dispersion colour to the glass+ colour to use dispersion.
Update - 31-08-2017
Now updated to include volume absorption (disabled by default)
Latest version is now v1.1 So when appending use the Glass+v1.1 material.
Cycles is great and all. But Glass BSDF is severely lacking.
INTRODUCING...
Glass+
"Wait whats wrong with Glass BSDF?"
1) The default IOR is 1.45, glass is not plastic, the IOR of crown glass the kind most commonly found in everything from glassware to windows is 1.52 something thats annoyed me for a long time.
2) Noise, noise and more noise. Glass BSDF is noisy especially for interiors. Glass+ eliminates that with use of the light path node, but instead of doing it all the time Glass+ is configured out the box.
3) Glass BSDF has roughness but no bumps. Glass+ does. Even mirrors have bumps.
To demonstrate this the Glass+Demo.blend has an exact duplicate on layer 1 and layer 2
Layer 1 contains the example render at 20 samples, standard Glass BSDF
Layer 2 contains the exact same thing at 20 samples, this time with Glass+
This is a pretty cool material. I would like to say though, your criticisms of the Glass node are somewhat unwarranted. The Glass node is good for what it is, a basic PBR simulator for reflective/refractive materials, commonly used to simulate glass. I would like to add that, technically, by using the light path input, you are making it less physically based (at the benefit of reduced noise and more). I don't believe the Glass node is meant to be a complete simulator for all types of glass materials. Yes, many reflective/refractive materials have visible surface displacements; that is what the normal input is for (also the displacement input on the material output). The Glass node meant to be a lower-level base node used to create more complex materials (as you have done). I think you did a good job on this material, I just disagree that the issues you have the Glass node are actual shortcomings.
