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.

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.

How to get the render pixels coordinates in compositing
When fine-tuning the finished render in “Compositing”, sometimes it is necessary to refer to the pixels coordinates of the processed image, for example, to apply effects distributed over the entire width or height of the image.
We can get the distribution factor of coordinates along with the height or width of the rendered image using texture nodes.

How to show all available nodes
We can get a list of all available shader nodes by their type.
To start, add any object to the scene, for example, a cube, create material for it, and delete all nodes. Here, in this material, we will display all the shader nodes available in Blender.
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.

How to make node connections in Blender 2.8 not straight, but curving as before
In Blender 2.8 node connectors in the “Shader Editor” window are straight by default, unlike earlier versions, where they bent curving. To return the usual connections bend, change the following settings:
- Open the “Preferences” window
- Switch to “Themes”
- Expand the “Node Editor” tree branch
- In the “Node Curving” field, set the value greater than 0. 0 means straight lines, the larger – the greater bend. A value of 4 corresponds to the bend that was in Blender 2.7x versions.
How to randomly shift texture on objects
To shift the texture randomly on different objects, the easiest way is to change its location along any of the axes by a random value.
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.
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.
Node Font – font shader by nodes
Procedural shader with Latin font made with Blender nodes.

Available in the BIS library.
Simple way to manage the SSS radius
In Blender 2.81 with the “Vector Math” node we can simple regulate the subsurface radius:

Hans Chiu shared a stream about making a procedural animated zipper material.
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:
EEVEE Shadow Catcher
There is a convenient opportunity in the Cycles render engine to render an object with shadows on a transparent background using material with the “shadow catcher” option. There is no such material in EEVEE render engine, however, in EEVEE we can make our own “shadow catcher” based only on nodes.
Completed “EEVEE Shadow Catcher” material you can get from the BIS library.
Lighting with textures
In Blender Cycles using common lamps we can illuminate objects with any texture, not just a single color.
Add an object, for example – sphere, to the scene:
shift+a – Mesh – UVSphere
and set a simple diffuse shader to it.
How to make a pattern from the single element of the BIS library
A single procedural element from the BIS library can be easily transformed into a repeating pattern.
Let’s get a single circular elemetn from the library and place it in the center of the plane.

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.
Node displacement in Blender 2.8
In Blender 2.8, the displacement node in Cycles render-engine was changed from scalar to vector. If you simply connect a black and white height map to the Displace input of the material output node, like in Blender 2.7, it will not give the desired result.
To make the correct node displacement in Blender 2.8 add “CombineXYZ” and “VectorDisplacement” nodes to the material node tree. Connect the height map to the “Y” input of the “CombineXYZ” node and its “Vector” output to the “Vector” input of the “VectorDisplacement” node. After that, connect the “Displacement” output of the “VectorDisplacement” node to the “Displacement” input of the material output node.
Decorators for node tree updation delay
When we create a field on the add-on interface panel, the value of which changes something in the node tree, each time the user changes the field value the node tree recompiles. If the user changes the value in that field by holding and moving the mouse, too frequent node tree recompilation will cause Blender to hangs.
This problem can be solved using decorators for deferred updating of the node tree.
