Oh, you're using the tutorial script.

I know you don't want to read anything, but this is from a tutorial, the point of which was to teach how to use this thing by have you read it. Every step was explained, and the script is heavily commented, reiterating what is going on. If you don't read the words, it's going to be useless. If you only read 3/4 of the words, it is useless.

This is not a script for generating a finished material you'd use in your renders. It is an exposition for learning how to use the parameters that the Loom offers. It generates a series of materials that demonstrate how the settings affect things. From this, you would learn how to assemble a script using the elements you want.

For example, this script says:

64 threads is a good number for demo on a one-sided square. My posted renders

were done with square filling the screen and a render size of 512 by 512 pixels.

N = 64

That is where the number of threads was set in the script.

Then later, one of the materials created was done so by this line:

outputs += ["RedOrange", loom.Generate(N)]

That is the line where the loom generates a material, with N threads. So if you changed N=64 to N=1000, then all the materials made by this script that use Generate(N) would be using 1000 threads instead of 64 threads. There are two other thread counts in this script, ZN and BigN, that I used for individual demos in the tutorial where I wanted to zoom in or out.

None of which is important for USING the loom.

The point of matmatic is to be able to assemble simple statements to make very complex materials. It is not useful for you to just generate the materials I posted. In that case, I could just give you materials and we could skip the matmatic part.

Do you want a pale blue twill with 500 threads per unit? Or a dark red herringbone with 750 threads per unit? Or a Glenn Plaid of cream and gray with 775 threads per unit?

You can make any of those with just a few lines of script.

If reading and understanding and learning from the tutorials and examples isn't helpful, then how about you just describe the material you want and I or somebody else will give you a script to do that. Then you can work with something closer to what you intend.

What weave pattern? What colors? How much fuzz? How many threads?

Besides the basic weaves supplied in the tutorial thread, you can choose any pattern from here:

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
