Hello everyone,

I use MaterialX in Solaris to have the universal project so that I can export it in USD afterwards.

Karma supports MaterialX but not Arnold (as a plugin in houdini).

Arnold just makes the USD preview and when I disable the auto generate preview, nothing more...

I can’t find any information on this subject on the internet.
If joint this finds a capture with karma (which works) and the other with Arnold (does not work)

Does he have a solution?


Thank you in advance

Sorry about my English

I am experiencing the same issue.
A scene containing MaterialX standard surface shaders, renders fine with Karma but not Arnold, the strange part is that the same USD file renders fine with Arnold in Maya (MtoA).

Karma :


Arnold :


Scene files :
Image Not Found



Using Houdini : 19.5.403
HtoA 6.1.3.3 (Arnold 7.1.3.2)


UPDATE : In my case it is HtoA version, MaterialX wasn't supported with USD.
