DR IM precalculation - only first frame rendered with all nodes

[pascalls]

Hi,

i searched for this subject but could not find solution.

I am trying to render IM prepass using DR but only first frame gets rendered with all nodes. Next and all other frames are rendered only with one computer, pc that i started rendering from.

I have checked the log and all looks fine there. I am doing DR all the time and it works OK all the time.

Doeas anyone have an idea what could be wrong?

I am up against a deadline and any help greatly appretiated.

Thanks very much!

EDIT

this is end of a log txt from one of the render nodes. Does this look ok?
Does this [2011/Mar/14|20:33:19] Image prepass completed line from the end of the log means that the prepas rendering has finished?

thanks

When i press escape to cancel rendering prepass, than i see brown message in the vray message window "server (ip address) starting frame ..." for all render nodes and than everything gets canceled

for me it works only when using "incremental add to current map".... the imap will not saved during rendering, it´s been written only into the RAM. on render end, I save the imap file manually from the render dialog... this my work arround to use DR for prepass calculation...

quick update if anyone is interested...

i have contacted vray and was told that they were able to recreate this problem at their end and are working to solve it.

update: If it´s a camera flythrou with static elements, just tick " use camera path" an render out one Frame... It calculates the whole animation prepass DR in one pass....
