I've searched both the forums and the store and I don't find any.
Here's what I'm actually wanting: A shader that can be loaded under any color texture tile to give the appearace of woven cloth.
I know that there is a "weave" texture under 2D in the nodes... I just haven't got the first idea here to plug it in. I susopect it is "bump" but my experiments are getting nowhere. If I could figure that out, the rest is figuring out sizes and offsets. I can probably manage that. I just need a little help getting started.
Anyone know the answers?

Exactly! Thanks!

You can find other patterns as images easily enough. You use them as bump maps or to multiply with the color, or both.
Here I'm using a twill bump map (upper left) and the plain weave node (lower right).

Could I see your mat room on these, BB?

Umm - sure but do you want to see the actual mats I used, which includes dozens of nodes not taking part in the bump? Or just the bump?
The bump is not worth showing and was already in the other threads. You connect the weave or image_map to the bump channel. You decide a number to put in the bump channel that depends on the gray level of your source data and your Poser display units.

The Blender is optional. I used it to get some baked-in occlusion shadowing in the cloth. Whether that is needed or not depends on a lot of factors. Try setting the Blending value to less or more and learn how it changes things. It will depend on the map you use too.
My Poser Display Unit is inches, so that multiplier there is .05 inches. Whether you need that or a different value also depends on the image.

Personally, I use the weave node in demonstrations because everybody has it, but I don't use it in practice. Few fabrics are woven that way and when I use it everything has the look of bandages.
Twill is much more realistic. Blue jeans are twill. Oxford shirts are twill.

I suppose I should note also that the Matmatic Loom can make any weave you want.

Wow. Very simple. BTW... where did you get the mat? Is it available?

I image googled "weave bump map". First result.

As always, BB, you are a wealth of information! Many, many thanks! This solves a lot of wishes for me.

Also falsehoods. I wrote twill is Oxford above. Not so. Oxford is plain (aka basket) weave - i.e. the weave node.

If that's the worst mistake you make today, you are golden!
