Pretty straightforward, but where can I expect this node to be supported? If I needed to use Arnold or Renderman in Houdini and wanted to use materialX, would this work? I imagine that it's a Houdini-specific node but I wanted to see if it's also Karma-specific.
Also, am I right in assuming that it's not doing 4 texture samples to account for 1 UV and 3 triplanar samples? Because if so, that definitely makes it more appealing to use.
