1.45.70 g-buffer channels with netrendering?

[plastic_]

how do i save g-buffer channels when netrendering with backburner?
when the vray framebuffer is activated i can save the channels with the "save seperate channels..." option in the framebuffer rollout.
but when netrendering nothing is saved. (yes, i tried UNC paths).
also no error.
is there another way to save them?
i'm especially interested into the reflection&refraction passes and the object velocity.

nevermind...it works now.
i dont know what i was missing at the first try.

but for some strange reason 2 channels are rendering...RGB_Color and Alpha. but i only selected Object velocity, and that one is missing.
