When I saw that @Mohsen_Tabasi created the hextile HDA for procedural texturing large areas without getting repetition I wanted to use it with Karma XPU. Unfortunately this didn't work because of cvex.

So I thought of recreating the HDA, but then for Karma XPU / MaterialX!
Although I came across quite some surprises and had to do a few workarounds. IT WORKS!

The HDA can be downloaded here in the attachements!

It also works with displacement, although I ran across some issues.


One of the issues is the obvious hexagon lines in the image above. The image filtertype here is set to closest, which does actually give the best results (like the picture), but I guess the checkerboard picture is maybe 'too much' to try this effect on. When using regular texture these lines sort of mostly disappear.
