I have 2 questions: 1) I don’t understand the use of the "Transparent Depth" in the Light Path node at 6:20? If I’m right, rays that pass a transparent object are shaded according to the “Transparent BSDF”. But in your scene there are no transparent objects, so the glass won’t be shaded as transparent right? Aren’t these nodes essentially unnecessary? 2) I also don’t understand What “Transmission Depth” and “Layer Weight” does at 16:47. What condition does that set for the “Mix shader”? You mix ‘white glass’ with ‘RGB glass’, but how is it mixed exactly? Thank you in advance! :)
