Archviz Props - Glassware With Phisically-Based Glass Shader
Is it 2.80 only?
As of now, yes. I don't plan to release a 2.79 version, as it is soon bound to expire. However you can still use the collection by appending single objects in your scene, which is also the most common way to use a library anyway
Is the glass shader different from the others or the original Cycles one?
Yes, it has been created specifically for this collection. While it may not be an all-around shader suitable for every purpose, it is well suited for crystal glassware, adding the right amount of reflections and following a physically-based approach
