I've been having issues with rendering objects with materialx, The objects look faceted as if the objects normals aren't properly working. With principled shaders everything is fine. I'm using version 19.5.422, but this seems to be an issue with all versions. How do I get smooth normals with materialx shaders? Thanks

Is this also visible after rendering to mplay or on disk?

Are you using normal maps? I was having a similar problem at first and found that my problem was that I had forgotten to set the Signature in my Image nodes to Vector, so Karma was assuming the normals were sRGB and 'helpfully' linearizing them for me.

Yes. I think this was my issue. Thanks!
