Mapping node for Geometry Nodes
The Mapping node does not exist in Blender Geometry Nodes by default. However, we can build it ourselves.

Mixing materials by the UV coordinates
UV coordinates can be used for mixing materials directly on the mesh. This can be useful if, for example, the shape of the mesh is cylindrical or closed or the UV boundaries correspond to the boundaries of the mesh.
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.
Ortho lighting
When the scene is lighted with “Spot” or “Point” light sources, the rays from such lamps do not propagate in parallel. This makes noticeable distortion, for example when lighting with textures.
The parallel ray’s propagation (orthogonally to its plane) we can get from the “Sun” lamp, but such light source does not support lightning with textures.

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.

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:
