What Max material to use for best fidelity when exporting USD?

[Gurpgorn]

I've had a lot of issues with materials looking very different when exporting from Max to Nvidia Omniverse. Is there a prefered kind of material to use for best fidelity with USD?

Sorry it took so long to get back to you. The best options are to use the USD Preview Surface Material for simple materials. For more complex needs, you can use the MaterialX Material. Both are available in the material editor when the Max USD Plugin are installed.
