Vraybumpmtl not displaying in standalone RT

[drew_almighty]

I recently used a vraybumpmtl to quickly add perforations to a leather shader. Works great when rendered with full V-Ray or V-Ray RT in Maya, but when I see the RT image in V-Ray standalone the geometry is completely black. Is the vraybumpmtl shader not supported by the standalone RT? I haven't found anything that says one way or the other...

It should work fine; can you post a .vrscene that has this problem?

Best regards,
