Inverting 1 to 0 and back with nodes
In order to make an inversion of the boolean value: invert 1 to 0 and 0 back to 1, we only need to use two Math nodes in the Blender node editor.

Mixing maps in Blender
In order to mix two normal or bump maps in Blender shader so that they overlap as required, we need to correctly connect their nodes in the Node Editor.
Quick fake reflections for toon shaders
For some toon shaders, it can be difficult to set up good reflections. the principle of non-realistic shading prevents the scene lighting from being processed correctly.
However, in the EEVEE render engine, we can set up fake reflections for toon shaders, which will look good and render quickly.
A shader pack by Erindale Woodford from the Nodevember 2020 event
Erindale Woodford, the creator of very complex and advanced shaders, has released all of his shaders from the Nodevember 2020 event.
A pack of 30 shaders can be downloaded from Gumroad.
All shaders are available for free for personal and commercial use.
Error when using an OSL shader with node_texture.h
If the OSL shader body contains an import of the “node_texture.h” module, this shader can’t be executed in the latest versions of Blender.
When trying to execute such a shader, Blender throws an error:

error: could not find include file: node_texture.h |

Nodevember 2020
“Nodevember 2020” – the next challenge is coming from November 1 to 30 for amateurs and fans of procedural (node-) modeling and creation. The rules of the challenge are very simple – each participant creates one procedural material/object on a given topic each day with Blender exclusively using nodes. You can create whatever you want – models, meshes, materials, shaders, and even music, as long as they are procedural. Next, publish your created object on social networks with the #nodevember hashtag.

Blender EEVEE transparency blend modes – Multiply and Additive
In Blender 2.83 in the EEVEE render engine the “Additive” and “Multiply” modes that were present in Blender 2.80 were removed from the possible transparency blending modes.
But if you need to use these transparency blending modes in Blender 2.83, you can get them with nodes.

Glass shader tuning for Cycles render engine
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:
