When relations were set, might it be recognized to be Duplication object?

I think that it was always rendered like that in internal renderer.
The result is the same in 2.49b.

Support for the particle system is on hold since the entire pipeline needs a rewrite to fix bugs in a way they don't cause other issues.

Thanks for the report @AndreiIzrantcev, but for now I'm afraid we can't help you much.

Tnx for looking into this. Basically all I need to know right now is which variant is correct (since I'm writing V-Ray For Blender and I need to know how to handle such a setup). Personally I think Cycles version is correct.
