Modifiers not working with RenderMan?

I’ve been trying out RenderMan for a few days, it’s really nice…but is there any way to get modifiers like array and bevel to work with it?

There’s some strange (bug like) behavior if you don’t save your file first. After saving, everything is back to normal, OK.

Example:

scene file: b2prman_array-bevel_modifiers.blend

Oh, thank you! I guess that also explains why after I delete an object it still shows in the scene.
