In case anyone's interested, here's a handy woven cloth texture. To add color,
you can add another texture to the averaged texture_map near the end. I hope
someone finds this usefull!

Thanks a lot indeed. I always use an image map for this effect, mostly as a
bump map (as your texture can also be applied of course), but it is nice to
have it as a texture code.

looks a lot like the one used in Gimp too. Perhaps similar algorithms? :)

Simple and neat solution,

I think it would be even more useful if it had a 'normal' block as
well. That way it would interact with lighting, giving it depth.

Hmm, I could use this as a starting point fore a carbon fibre texture :)

I tried to do this myself, but didn't get anything useful. Maybe it's
harder than it sounds.

I tried adding a little turbulence the texture pattern, rendering once in
gray and again with a colored pattern, then imported the gray as a height
field and the pattern as the color, and made a pretty neat shape. I made
real gaps in the shape with the water level. I think you could do a pretty
good picnic basket or some such by UV mapping this output as a displacement
map, too.
Bravo, I like this. :-)

Most Excellent. I tried to come up with something similar a while back,
but failed. This works great.
