Just goofing around today and make these depth maps for 3D engraving. One is a 2x2 twill (herringbone) weave and the other is a satin weave pattern.
These should tile pretty well.
I made these in Inkscape by the way. If anyone wants the SVG files I can add them, but these were vectors that were converted into bitmaps within Inkscape then cropped to make the tile.
Those are very nice. Thanks for sharing them! 
Prettttttyyyyy
Thanks!
I’m going to try adjusting these a bit. I just loaded them into ZBrush to make into 3D models and the gradients came in a bit linear instead of having a slight curve like intended…
OK I have updated the files and attached them to the original post in this topic. These gradients will produce a smoother curve profile, or at least should, depending how your particular software reads images for depth maps.
Super cool!
