3dsMax USD Stage object has a fallback mode which any CPU renderer can benefit when they don't have native USD rendering yet.
Basically, 3dsMax will convert USD stage object as rendermesh while rendering. Then user can use use as another way of referencing. You can even override materials.
The problem is that... when I load an USD file with Stage object and render in Corona. it shows facet result. All other CPU renderer don't have the issue. I tested with Scanline, Arnold, Final Render.
This is the render of Apple toy drummer USD file.
