MaterialX v1.39.2 also brings improvements to the classic Worley noise technique, contributed by Chris Rydalch at SideFX and seen here in Karma for Houdini.

Another key contribution is generic color ramps, authored by Jonathan Feldstein at Autodesk and seen below in Arnold for Maya, allowing a new level of flexibility for color controls in MaterialX graphs.

I wanted to highlight this recent proposal from Masuo Suzuki at NVIDIA, adding support for Mikkelsen's classic Hex-Tiling technique in MaterialX.

We'd love some feedback from the graphics community on this proposal!
