A fuzzy cloth like material created in blender (mastodon.art)

Trying to get comfortable with the shader nodes in blender I sometimes create random materials. I mostly post them on my mastodon account but I will test the waters here as well.

The basic idea for the shader is to get two weaves going at 90 degrees from each other. I used a voronoi, scaled down in one direction to make each bit long rather than round, with a low randomness to make each weave. Then pipe it into normal and displacement maps to get the texture out, and use a colour ramp to add the albedo and some light subsurface scattering. Tinkering with the bsdf is just me playing with slider, I didn't have any real direction with those.

If this were going to be for a photoreal material this node set up would be an excellent base to start from, but it would take many more layers and details to use.

What do you think? Do you have any suggestions for materials for me to try?

Isn’t colour data a vector of the r g and b?

Yeah and since it's basically a grayscale image with identical RGB values, the normal map ends up representing some weird surface with the normals being on a single line between (0,0,0) and (1,1,1). I guess the bump node finds the slope of the grayscale instead.

I think in Eevee the Displacement node does the same thing behind the scenes, so having both displacement and Bump + Normal Map deriving from the same height data will probably double the effect.

Yes. This was in cycles with adaptive subdivision on the model though so the displacement was actually displacing the geometry and the normal map was for adding a little more pop without displacing the geometry more than I wanted

Nice, I work mainly in Eevee for game assets so I have to add the geometry manually. I wish they added more real-time rendering features from game engines (like parallax mapping), would make previewing much easier. The new realtime compositor is almost good enough for protyping post-process shaders in blender but they still don't support render passes unfortunately.
