RTX raytraced glass

Glass material tests in Toolbag 4. This is a homage to the first college assignment I did while learning 3D modelling, I made a single sherry glass and rendered it with raytraced reflections, refractions and shadows with 4 lights and it took 25 mins for a 640x480 image, back in the days of 3dsmax 2.5. These days I can look dev 300 glasses in seconds using Nvidia RTX and Toolbag 4. Imperfections on the glasses were achieved with a subtle normal map and some blurry noise as roughness.
