How to make a procedural texture from multiple images?
I would put them into a single texture into a grid of unique tiles and then use math to manipulate texture coordinates and noise textures for randomisation:
You could also use the same principle, to ...

How to make a procedural texture from multiple images?
This method is pretty much the same as Martynas'.. I thought it was going to be lazy, avoiding the math by using a non-random Voronoi to do the grid.
It subtracts the 'Position' of the Voronoi from ...

How does Normal Texture Coordinate work?
Texture coordinate/normal outputs the object space normal, a unit-length vector.
If we separate the Z component of that, we're getting the amount that the normal extends in the object-space Z axis.
If ...

How would you make a procedural displacement texture resulting in random planar faces?
New Answer:
I have adapted my first approach a bit and also fed the Normal slot of the Glossy Shader to create the impression of a perfectly flat surface. If you want to also achieve the beveled look ...

Emulate "Sphere" image texture in Geometry Nodes
Sphere Projection uses the Spherical coordinate system:
radial distance $r$ (or $ρ$) is not used, because it’s a projection,
azimuth $\varphi$ (also known as a polar coordinate) is translated to $x$ ...

How to mask texture with normal?
As taiyo describes in his answer, The "Color Ramp" always gets 0.5 value, for which it always outputs white color, which could be replaced with "Combine XYZ" node with $<1, 1, 1&...

How to mask texture with normal?
The key observation is that you plug (1,1,1) into the normals. This normal is spread across the donut and divides it into two parts: one where the normal is sticking out of the surface and one where ...

seamless circular coordinates
If you pop into 3D, you can pick up coordinates which are seamless there, and map those to a flat circle, one way or another:
Here, the wall of an (imaginary) capless cylinder is tapered to a cone, ...

Automatic Image Texture mapping (Scale and size) on surfaces (no UV maps)
You can work with the UV Project modifier. This modifier works with an empty object which helps you to project the image onto the mesh faces. First you need to add a new UVMap to mesh
Then with mesh ...

How to rotate texture 90 degrees when using Object texture coordinate?
For those who are also searching for a solution for rotating Object texture coördinates, I found a way by using the normal texture coördinates of the object. By attaching those to vector rotate node ...

How to use the contact area between the instance and the mother object as texture coordinate in shader?
If you use Boolean Mesh, you can not only sum up the area of mesh islands but also create such geometry, that there's a separate shader for the insides of the droplets, getting rid of the problems of ...

Why is the UV being distorted when transferring to a copy of the model?
I haven't solved the specific problem, but I have solved the main issue. Turns out Unity can automatically make lightmaps. I'm uncertain about how efficient it is, but it works on this model well.

Why is the UV being distorted when transferring to a copy of the model?
When going back and forth between programs, sometimes the vertex indices get changed (reordered). Since UV maps are basically 2D coordinates stored on vertices (face corners really), mixing up vertex ...
