https://youtu.be/rHZnQAnqLdgArchViz Glass is meant to be used on everything from window planes to high resolution ArchViz props. Includes the ability to import custom Base Color, Grunge, Normal, Ambient Occlusion, and Thickness maps. Complete control through parameters that allow refinement of BaseColor, Specular, Metallic, Roughness, Opacity, Normal, and Refraction. Within these, there are Grunge and Refraction controls. Fine tune these to achieve exactly the look and feel of the glass you'd like.
Huge thanks to Kevin Theesfeld for his immaculate help refining and troubleshooting.
