Maya 2020 MTOA "Export to MaterialX" exports invalid document

[frankieliu]

TextureStandardSurfaceExport.mtlx.txtIn MtoA 4.0.3.1

Export Selection to MaterialX 1.37 seems to export invalid docs for 1.38

It produces invalid nodedef and mismatched types for port connections.

What is the status of this Utility? Is it supported?

Note: Changed extension because I can't upload .mtlxash_uvgrid07.jpg

Arnold doesn't support MaterialX 1.38 yet.

Where you are you using this mtlx file? I didn't have any problems with it and 1.38

afaik, this utility is intended for moving mtlx files between Arnold plugins.

I tried loading it using the Pre-built MaterialX bindaries for Windows.

I don't think the MaterialViewer knows about Arnold nodes. Things like standard surface are going to work only with Arnold plugins.
