To make glass objects render faster and cleaner in Cycles render engine, we can adjust glass material processing by the number of beam bounces.

Random Per Island
In Blender 2.82 we can get a random index of UV islands in the Shader Editor through the “Geometry” node
Works only for the “Cycles’ render engine.
Global materials override for the Blender EEVEE render engine
Some times we need to make a render of the scene with the single material, for example, for clay or wireframe renders. Blender has the global materials override option for the Cycles render engine in the “View Layer Properties” – “Override” but not for the EEVEE render engine.
Quick materials override for the EEVEE rendering engine can be made with a small script, as shown in the following video:
Script and video by Vitaly Sokol.

Base PBR-materials scheme
The basic scheme for making a PBR (physically based) node shader in Blender looks like as follows:
Note that all the “ImageTexture” nodes, except for the “Base Color” node, use the “NonColor” colorspace.

Nodevember
Nodevember is a monthly challenge you invited to make procedural objects for Blender every day. It can be a material, a shader, an object, anything, if only it would be procedural. “If you can call it nodes, you can call it Nodevember!”

Get Specular reflections from IOR
The official Blender documentation provides a method to get the “Specular” value for the PBR-material reflections if the “IOR” value is known. To get the “Specular” value from the “IOR” value, we can use the following equation:
It is not difficult to create it with nodes:

Radial Lightning
Procedural gradients
Except for the “Gradient Texture” node, we can obtain a gradient factor by using some simple equations. Look for the mathematics with a spherical gradient sample.
- Uniform gradient
Can be created based on a downward-facing cone equation.

Texture pixelization
The simplest way to pixelate texture, procedural or not – get the color from the single pixel and fill the region with required width and height (resolution) with this color.
Here is the gradient texture with red – green – blue colors:
To pixelate it with the first step of resolution we can make some vectors manipulations.
