Rendering Arnold USD on Point Instancer not working

[doppelgaenger_digital]

On the latest Bifrost Version 2.5.1.0. it seems, that rendering USD assets with shaders, exported either with Maya Dialog or Arnold USD export isn't working on a USD Point Instancer.

Rolled back to 2.5.0.0

It is working fine here BF 2.5.1, the latest Arnold 5.2.0, and USD 0.19. I exported 2 different ways and both worked.
