network render prepass?

[bradpski]

hey, i just recently started rendering using 4 computers (inclucing mine) and my question is that when i render using just my own computer the irridecent map usually takes 3 or 4 passes (depending on what level i ask for) but without changing anything except using network render, it only does one prepass before rendering???? just wondering why this is??

thanks. brad.

Did you uncheck multi pass and not notice?

Do you mean Distrubuted Rendering or network rendering thro backburner??

i am using distributed rendering on my network

this is how DR works... it calculates all the no. of passes for each bucket at once, rather than calculating prepass 1 for the entire frame then prepass 2 for the entire frame it calculates prepass 1 then 2 the 3 etc for each bucket so once its covered the whole image its ready to render.
