Add the Gabor Noise Texture type, this type of noise can be used to create fabrics and add surface imperfections: https://www.youtube.com/watch?v=f3_EZbrUUQs https://graphics.cs.kuleuven.be/publications/LD11FSGN/

There's this patch for Blender although it is written for OSL instead of GLSL: https://developer.blender.org/D3495

I am a super-noob at this fantastic app, but even to me it felt really easy to create something close to your example pictures using the built-in tools. Changing the values (like set the scale 0.2 to 0.4)/merging a couple of these should produce basically the exact same thing.

Sure, it's not as clean as just having a single neat texture node, but you get more control over the final result... (Cannot attach a source file, but here's a screenshot of how I made it:

You can compress the source file into a ZIP archive and upload it here :slightly_smiling_face:

Alright, I'll keep that in mind for the next one. This makes good immersion into the methods, though :)

If you find a nice combination of nodes you think is reusable, you might want:

to group them into a single node (select nodes you want to group and hit Control-G).
to expose relevant parameters (grouping created a Remote node, you might want to read docs about it).
you can then either store the result in your user library (Tools->Add selected node to user library) or into a file (edit->Save selection). You can also share anything you want by just copying nodes, and pasting them in a text-sharing service (pastebin).
