CG-Lion Architectural Glazing Presets Pack 1.0 is an custom architectural glazing shader I developed for Cycles render engine, that provides easy setup of real world architectural glazing surfaces, and ships with 40 ready to use material presets.
The shader has architecture-friendly real world parameters like ‘frosted‘, ‘milky‘, ‘smoked‘ glass etc., has convenient built-in inputs for effects like selective sand blasting or selective graphic coating and is internally optimized for transparent shadow casting.
The shading normal‘s Z component can be easily used as a ready-to-use procedural mask for ‘covering effects’ like dust, snow, and if baked, also as a base for particle effects like debris and vegetation.
This simple shading flow example the shading normal‘s Z component, that represents how much the surface is facing upwards is separated , mixed (multiplied) with a noise textured and than fed into a ColorRampConverter node for fine tuning the resulting mask:
This is the full shading flow of the snow effect in the image above:
