WINDOWS ONLY

Python script to create windows Batch file to launch Nuke renders by command line. It's less memory consuming
Plus some options like :
render "frame by frame" which allows to flush properly the memory for each frame. Some comps (same thing with Eyeon Fusion) tends to increase rendering time all along the process.
"skip existing frame" for deleted bug frames or deleted modified frames to avoid complicated frameranges.

it creates BAT executable files name like : "compName_WriteName_x1x450-525_FrameByFrame"

These scripts are inspired from Tim BOWMAN's "bgNukes" and Jep HILL's "skip existing renders" scripts .

ClrenderDialog2

 to install add these lines to your menu.py

import CmdLineRender

menubar = nuke.menu('Nuke')
m = menubar.addMenu('Nukepedia')
m.addCommand('CL Render', 'CmdLineRender.CLrender(nuke.selectedNodes())')

Sorry to ask what is probably a very straightforward question, but I'm getting:

Traceback (most recent call last):
File "C:/Users/Marti n/.nuke/menu.py ", line 9, in
m.addCommand('C L Render', 'CmdLineRender.CLrender(nuke.selectedNodes())')
NameError: name 'm' is not defined

What have I done wrong? The CmdLineRender.p y is also in the .Nuke dir.

Cheers.

Hi Martin,
It's an omission from me, sorry for that. I put in my own menus and didn't written the whole thing to work straight.
But for a general purpose we can put it in the Render Menu, so the lines should be :

For example
m = nuke.menu("Nuke")
m.addCommand('Render/CL Render', 'CmdLineRender.CLrender(nuke.selectedNodes())')

Thanks for the report,
Cheers,

what is the command to get all write nodes in the nuke script ?

Hi Sanjeev
you can add this line to have this behaviour :
m.addCommand('Render/CL Render ALL', 'CmdLineRender. CLrender(nuke.a llNodes('Write' ))')

Cheers

well we need to run this script from within nuke , right ?
 
 
0 # Philippe HUBERDEAU 2012-12-11 10:12
it's meant to be written in your menu.py, so yes kind of within nuke.

Hello

Is there a way to get it to render chunks rather than rendering a single file closing out nuke / reopening rendering a frame then closing out nuke / reopening nuke rendering a frame....
 
 
0 # Struts Alex 2017-05-28 00:56
Thanks Philippe! Useful tool! does not work "skip existing file"
 
 
0 # IDontWant ToRegister 2017-06-21 20:16
Seems to be broken with nuke 10.5v4
Skip existing file just reports an error
Regular rendering just hangs in there doing nothing.
 
 
0 # Dale Carman 2017-07-21 18:07
looking at the command string that it creates, I don't see where it is rendering every X frame.

with a regular nuke command line render you use -F 1-100x4 to render every 4th frame. When I have it split into multiple BAT files, I get
1-100
2-100
3-100
4-100
but I don't see it adding the x4 anywhere
 
 
0 # Dale Carman 2017-07-21 18:32
Also, sometimes, the bat files work and sometimes, I get this...

\Dale\Nuke\Dale\CmdLineRender.pyc was unexpected at this time.

hi there! Although I have a "create a write directory if non existent" When I activate the command line it gave me the "can't write. No such directory" error.
