Optimized Architectural Glazing for Blender & Cycles

Software:
Blender 2.8 | Cycles Renderer

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.

CG-Lion Architectural Glazing Presets Pack 1.0 is available for purchase on Blender Market.

Cycles render – Using the Normal Blue channel for top side effects

Software:
Blender 2.8 | Cycles Render

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 ColorRamp Converter node for fine tuning the resulting mask:

This is the full shading flow of the snow effect in the image above:

Complex Fresnel texture for Cycles

Software:
Blender 2.79 | Cycles Renderer

The most realistic way to create real world metal shaders is to use Complex Fresnel reflection.
Cycles has a general implementation of a Complex Fresnel reflection in its Principled shader (when Metallic is set to 1.0), but this implementation doesn’t allow using real world physical numeric Complex IOR values in order to accurately render physical metals.

You can use a Complex IOR OSL shader such as this one from Chaos Group,
But there are some limitations with it:
1) It isn’t supported in GPU rendering.
2) For some reason I don’t know I couldn’t get it to work with Cycles..

Seeing these limitations I decided to develop a Complex Fresnel/IOR texture for Cycles that will work on GPU, and your welcome to download it here on my studio’s website:
https://cg-lion.com/2018/07/08/free-complex-fresnel-texture-for-blender/

The blend file itself contains a text with some Complex IOR preset values for metals,
And you can get more physical IOR data from refractiveindex.info

Enjoy! 🙂

Realistic Spotlights for Blender & Cycles

Software:
Blender 2.79 | Cycles Renderer

There’s currently no built-in support for IES light sources in Blender & Cycles.
We already know that Blender 2.8 will have the feature built into it (which is great news!), and there’s an addon that provides the functionality, but I wasn’t satisfied with it’s workflow, not being integrated well into Cycles.
So I decided to develop a custom Cycles shader (node group) that will provide realistic IES like spotlights in a convenient customizable way.

The Shader I developed is called CG-Lion Spotlight Presets Pack 1.0 and is available for purchase on Blender Market.
It doesn’t load external IES files, but instead has a pre-configured library of 20 spotlights shapes, and also provides features that are not available in IES lighting like tweaking the spotlight beam focus, adding a chromatic dolor dispersion effect, and producing a correctly bright surface at the light source.
