Before I file en RFE, I though I would ask here what people think.
I noticed the UsdMtlx (MaterialX File Format and Shader Plugins for USD) is not part of the USD installation that comes with Houdni-18.
Would it be useful/complicated for SideFX to include it in a future build? I would certainly like to start playing with the possibilities it provides since our renderer of choice supports exporting mtlx files.

Houdini currently has no support for MtlX, in LOPs or otherwise. Because of this we don't have a MtlX library built/shipped with Houdini, so we can't build/ship the USD MtlX plugin. If you build your own MtlX library, you can then build the USD MtlX plugin against your MtlX library and the USD library that ships with Houdini. But I'd be reluctant to ship the MtlX USD plugin when we don't have any support for authoring MtlX shaders in Houdini, and I'm not aware of any third party renderers available for Houdini that understand MtlX shaders, let alone understand how to consume MtlX shaders saved as USD and sent to a render delegate (though I may be mistaken about that).
So it would be quite a bit of effort on our part, with questionable gain. And for individual customers, there is the option of building the required plugins for yourself, so there is a workaround.
Not to discourage anyone from voicing support for this feature here. If we are wrong about the importance of supporting MtlX, we'd certainly like to know!
