cinema 4d multipass rendering to deadline

Deadline
1

Hi Guys,



I am submitting a multipass render to deadline from cinema 4d. The multipass render is a motion vector.



Locally, the image files are output to one directory, and the motion vector pass to another directory, and all functions correctly.



When submitting to deadline, everything appears to work, but we just get two copies of the images. The multipass render directory doesn’t contain the motion vector, just another copy of the image renders.



Any ideas?



Kind Regards,

Hi Tig,



Try rendering the same multipass render from a command line prompt using

the same render arguments that Deadline is using. You’ll notice in the

slave window that Deadline prints out the render executable and command

line arguments it’s using to render the C4D job, so you can use that as

a reference. If the scene file is no longer in

c:\deadline\slave\jobsData, just copy it locally somewhere and change

the path as necessary in the command line argument.



The reason for doing this test is to see if you run into the same

problem when command line rendering with C4D outside of Deadline. I’ve

seen issues with multipass rendering from the command line in the past

with C4D, and I have a feeling this is another related problem.



Cheers,

Hi Ryan,



Thanks for your fast response, we greatly appreciate it.



Yes the command line render has the same behaviour as described. So obviously not a problem with deadline propagating the file etc.



Do you have any idea on a workaround if you have encountered this problem in the past. (will take this up with c4d guys but if you have any tips would be greatly appreciated)



once again thanks for your help =)

Hi Tig,



Unfortunately we aren’t aware of any workarounds for this problem. If

the C4D guys have any suggestions or workarounds, please pass them on.



Thanks!

Ryan,



This page led me to believe multipass should work from command line (note -omultipass option)



http://www.maxoncomputer.com/faq_detail.asp?idnum=1977



In their example they mention psd format, so as a punt, i tried the multipass with a different output format (PSD) and it worked.



Talking to the 3d freaks here i also tried it with openEXR and it worked like a charm - hope this might be of assistance if you need to do multipass…

So does this appear to be a TIF format issue? Or does the multipass

rendering only seem to work when including the multipass argument in the

command line options? If it’s the latter case, that would seem odd

because according to the documentation, it just replaces the multipass

path. It doesn’t say it ENABLES multipass rendering.



-omultipass /imagename/

Replace /imagename/ with a full path to override the Multipass Save path

stored in the file. The frame number and pass name will be automatically

appended for sequenced renders.





Thanks,

its a TIFF issue. when you use tiff as the output, the commandline multipass doesn’t work. (strange that it DOES work from within the gui)



-omultipass just specifies a new output directory, as they describe. it doesn’t affect the tiff problem, its just that this was my clue to try another format, because they we’re using .psd in that -omultipass parameter.



so i tried PSD and openEXR and both worked directly through deadline plugin.

Cool. Thanks for clarifying!
