Exporting to `mtlx` file & usd?

[ItsCubeTime]

Hi, sorry to intrude in your repo. But is there any chance we could get to see some priority going into exporting mtlx & usd?

It feels like having Hydra in Blender doesn't really have any practical use case until this is implemented - as Hydra Storm isnt meant to produce final pixels anyway.

Hi there, also interested in exporting mtlx files from blender shaders for nodes that are supported. Not sure if this is something that is going to be supported by early builds of blender or the hydra render engine addon, or only activated for usd (usda, usdc etc) scene files.
